PIC32MX5XX/6XX/7XX 2.9 Configuration of Analog and Digital Pins During ICSP Operations If MPLAB ICD 3 or REAL ICE is selected as a debugger, it automatically initializes all of the Analog- to-Digital input pins (ANx) as “digital” pins by setting all bits in the AD1PCFG register. The bits in this register that correspond to the Analog- to-Digital pins that are initialized by MPLAB ICD 3 or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain ADC pins as analog input pins during the debug session, the user application must clear the corresponding bits in the AD1PCFG register during initialization of the ADC module. When MPLAB ICD 3 or REAL ICE is used as a pro- grammer, the user application firmware must correctly configure the AD1PCFG register. Automatic initializa- tion of this register is only done during debugger oper- ation. Failure to correctly configure the register(s) will result in all ADC pins being recognized as analog input pins, resulting in the port value being read as a logic ‘0’, which may affect user application functionality. 2.10 Unused I/Os Unused I/O pins should not be allowed to float as inputs. They can be configured as outputs and driven to a logic-low state. Alternatively, inputs can be reserved by connecting the pin to VSS through a 1k to 10k resistor and configuring the pin as an input.

Voltages on these pins, if VDD < 2.3V, should not exceed roughly 3.2V relative to VSS of the PIC32 device. Voltage of 3.6V or higher will violate the absolute maximum specification, and will stress the oxide layer separating the high side floating node, which impacts device reliability. If a remotely powered “digital-only” signal can be guaranteed to always be  3.2V relative to Vss on the PIC32 device side, a 5V tolerant pin could be used without the need for a digital isolator.

Two other instructions, Multiply-Add (MADD) and Multiply-Subtract (MSUB), are used to perform the multiply-accumulate and multiply-subtract operations. The MADD instruction multiplies two numbers and then adds the product to the current contents of the HI and LO registers. Similarly, the MSUB instruction multiplies two operands and then subtracts the product from the HI and LO registers. The MADD and MSUB operations are commonly used in DSP algorithms.

It is not intended to be a when change in pin state is detected comprehensive reference source. To • Operation during Sleep and Idle modes complement the information in this data sheet, refer to Section 12. “I/O Ports” • Fast bit manipulation using CLR, SET and INV (DS60001120) in the “PIC32 Family registers Reference Manual”, which is available Figure12-1 illustrates a block diagram of a typical from the Microchip web site multiplexed I/O port. (www.microchip.com/PIC32). General purpose I/O pins are the simplest of peripher- als. They allow the PIC32 MCU to monitor and control other devices. To add flexibility and functionality, some pins are multiplexed with alternate function(s). These functions depend on which peripheral features are on the device. In general, when a peripheral is functioning, that pin may not be used as a general purpose I/O pin.

Refer to All port pins have three registers (TRIS, LAT and Section32.0 “Electrical Characteristics” for VIH PORT) that are directly associated with their operation. specification details. TRIS is a Data Direction or Tri-State Control register Note: Analog levels on any pin that is defined as that determines whether a digital pin is an input or an a digital input (including the ANx pins) output. Setting a TRISx register bit= 1, configures the may cause the input buffer to consume corresponding I/O pin as an input; setting a TRISx current that exceeds the device register bit = 0, configures the corresponding I/O pin as specifications. an output. All port I/O pins are defined as inputs after a device Reset. Certain I/O pins are shared with analog 12.1.3 ANALOG INPUTS peripherals and default to analog inputs after a device Reset. Certain pins can be configured as analog inputs used by the ADC and comparator modules. Setting the PORT is a register used to read the current state of the corresponding bits in the AD1PCFG register = 0 signal applied to the port I/O pins. Writing to a PORTx enables the pin as an analog input pin and must have register performs a write to the port’s latch, LATx the corresponding TRIS bit set = 1 (input). If the TRIS register, latching the data to the port’s I/O pins. bit is cleared = 0 (output), the digital output level (VOH LAT is a register used to write data to the port I/O pins. or VOL) will be converted. Any time a port I/O pin is The LATx Latch register holds the data written to either configured as analog, its digital input is disabled and the LATx or PORTx registers. Reading the LATx Latch the corresponding PORTx register bit will read ‘0’. The register reads the last value written to the AD1PCFG register has a default value of 0x0000; corresponding PORT or Latch register. therefore, all pins that share ANx functions are analog Not all port I/O pins are implemented on some devices, (not digital) by default. therefore, the corresponding PORTx, LATx and TRISx 12.1.4 DIGITAL OUTPUTS register bits will read as zeros.

If SSRC<2:0> ‘000’, this bit is automatically cleared by hardware to end sampling and start conversion. 3: This bit is automatically set by hardware when analog-to-digital conversion is complete. Software can write a ‘0’ to clear this bit (a write of ‘1’ is not allowed). Clearing this bit does not affect any operation already in progress. This bit is automatically cleared by hardware at the start of a new conversion. DS60001156K-page 240  2009-2019 Microchip Technology Inc.

If a ‘0’ is written by the CPU, the transmit logic finishes the current packet’s transmission and then stops any further. This bit only affects TX operations. bit 8 RXEN: Receive Enable bit(1) 1 = Enable RX logic, packets are received and stored in the RX buffer as controlled by the filter configuration 0 = Disable RX logic, no packets are received in the RX buffer This bit only affects RX operations. Note 1: It is not recommended to clear the RXEN bit and then make changes to any RX related field/register. The Ethernet Controller must be reinitialized (ON cleared to ‘0’), and then the RX changes applied. DS60001156K-page 288  2009-2019 Microchip Technology Inc.

PIC32MX5XX/6XX/7XX REGISTER 25-1: ETHCON1: ETHERNET CONTROLLER CONTROL REGISTER 1 (CONTINUED) bit 7 AUTOFC: Automatic Flow Control bit 1 = Automatic Flow Control is enabled 0 = Automatic Flow Control is disabled Setting this bit will enable automatic Flow Control. If set, the full and empty watermarks are used to automatically enable and disable the Flow Control, respectively. When the number of received buffers BUFCNT (ETHSTAT<16:23>) rises to the full watermark, Flow Control is automatically enabled. When the BUFCNT falls to the empty watermark, Flow Control is automatically disabled. This bit is only used for Flow Control operations and affects both TX and RX operations. bit 6-5 Unimplemented: Read as ‘0’ bit 4 MANFC: Manual Flow Control bit 1 = Manual Flow Control is enabled 0 = Manual Flow Control is disabled Setting this bit will enable manual Flow Control. If set, the Flow Control logic will send a PAUSE frame using the PAUSE timer value in the PTV register. It will then resend a PAUSE frame every 128 * PTV<15:0>/2 TX clock cycles until the bit is cleared. Note: For 10 Mbps operation, TX clock runs at 2.5 MHz. For 100 Mbps operation, TX clock runs at 25 MHz. When this bit is cleared, the Flow Control logic will automatically send a PAUSE frame with a 0x0000 PAUSE timer value to disable Flow Control. This bit is only used for Flow Control operations and affects both TX and RX operations. bit 3-1 Unimplemented: Read as ‘0’ bit 0 BUFCDEC: Descriptor Buffer Count Decrement bit The BUFCDEC bit is a write-1 bit that reads as ‘0’. When written with a ‘1’, the Descriptor Buffer Counter, BUFCNT, will decrement by one. If BUFCNT is incremented by the RX logic at the same time that this bit is written, the BUFCNT value will remain unchanged. Writing a ‘0’ will have no effect. This bit is only used for RX operations. Note 1: It is not recommended to clear the RXEN bit and then make changes to any RX related field/register. The Ethernet Controller must be reinitialized (ON cleared to ‘0’), and then the RX changes applied.  2009-2019 Microchip Technology Inc. DS60001156K-page 289

Once a packet has been successfully received, this register is incremented by hardware based on the number of descriptors used by the packet. Software decrements the counter (by writing to the BUFCDEC bit (ETHCON1<0>) for each descriptor used) after a packet has been read out of the buffer. The register does not roll over (0xFF to 0x00) when hardware tries to increment the register and the register is already at 0xFF. Conversely, the register does not roll under (0x00 to 0xFF) when software tries to decrement the register and the register is already at 0x0000. When software attempts to decrement the counter at the same time that the hardware attempts to increment the counter, the counter value will remain unchanged. When this register value reaches 0xFF, the RX logic will halt (only if automatic Flow Control is enabled) awaiting software to write the BUFCDEC bit in order to decrement the register below 0xFF. If automatic Flow Control is disabled, the RXDMA will continue processing and the BUFCNT will saturate at a value of 0xFF. When this register is non-zero, the PKTPEND status bit will be set and an interrupt may be generated, depending on the value of the ETHIEN bit <PKTPENDIE> register. When the ETHRXST register is written, the BUFCNT counter is automatically cleared to 0x00. Note: BUFCNT will not be cleared when ON is set to ‘0’. This enables software to continue to utilize and decrement this count. bit 15-8 Unimplemented: Read as ‘0’ bit 7 ETHBUSY: Ethernet Module busy bit(1) 1 = Ethernet logic has been turned on (ON (ETHCON1<15>) = 1) or is completing a transaction 0 = Ethernet logic is idle This bit indicates that the module has been turned on or is completing a transaction after being turned off. bit 6 TXBUSY: Transmit Busy bit(2) 1 = TX logic is receiving data 0 = TX logic is idle This bit indicates that a packet is currently being transmitted.

Parameters are for design guidance only and are not tested. 2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages. 3: Negative current is defined as current sourced by the pin. 4: This parameter is characterized, but not tested in manufacturing. 5: See the “Device Pin Tables” section for the 5V-tolerant pins. 6: The VIH specification is only in relation to externally applied inputs and not with respect to the user-select- able pull-ups. Externally applied high impedance or open drain input signals utilizing the PIC32 internal pull- ups are guaranteed to be recognized as a logic “high” internally to the PIC32 device, provided that the external load does not exceed the maximum value of ICNPU. 7: VIL source < (VSS - 0.3). Characterized but not tested. 8: VIH source > (VDD + 0.3) for non-5V tolerant pins only. 9: Digital 5V tolerant pins do not have an internal high side diode to VDD, and therefore, cannot tolerate any “positive” input injection current. 10: Injection currents > | 0 | can affect the ADC results by approximately 4 to 6 counts (i.e., VIH Source > (VDD + 0.3) or VIL source < (VSS - 0.3)). 11: Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted pro- vided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the speci- fied limit. If Note 7, IICL = (((Vss - 0.3) - VIL source) / Rs). If Note 8, IICH = ((IICH source - (VDD + 0.3)) / RS). RS = Resistance between input source voltage and device pin. If (VSS - 0.3)  VSOURCE  (VDD + 0.3), injec- tion current = 0.  2009-2019 Microchip Technology Inc. DS60001156K-page 365

PIC32MX5XX/6XX/7XX APPENDIX A: MIGRATING FROM PIC32MX3XX/4XX TO PIC32MX5XX/6XX/7XX DEVICES This appendix provides an overview of considerations For example, to clear a UART receive interrupt, the for migrating from PIC32MX3XX/4XX devices to the user application must first read the UART Receive PIC32MX5XX/6XX/7XX family of devices. The code register to clear the interrupt condition and then clear developed for the PIC32MX3XX/4XX devices can be the associated UxIF flag to clear the pending UART ported to the PIC32MX5XX/6XX/7XX devices after interrupt. In other words, the UxIF flag cannot be making the appropriate changes outlined below. cleared by software until the UART Receive register is read. A.1 DMA TableA-1 outlines the peripherals and associated interrupts that are implemented differently on PIC32MX5XX/6XX/7XX devices do not support PIC32MX5XX/6XX/7XX versus PIC32MX3XX/4XX stopping DMA transfers in Idle mode. devices. A.2 Interrupts In addition, on the SPI module, the IRQ numbers for the receive done interrupts were changed from 25 to 24 PIC32MX5XX/6XX/7XX devices have persistent and the transfer done interrupts were changed from 24 interrupts for some of the peripheral modules. This to 25. means that the interrupt condition for these peripherals must be cleared before the interrupt flag can be cleared. TABLE A-1: PIC32MX3XX/4XX VERSUS PIC32MX5XX/6XX/7XX INTERRUPT IMPLEMENTATION DIFFERENCES Module Interrupt Implementation Input Capture To clear an interrupt source, read the Buffer Result (ICxBUF) register to obtain the number of capture results in the buffer that are below the interrupt threshold (specified by ICI<1:0> bits). SPI Receive and transmit interrupts are controlled by the SRXISEL<1:0> and STXISEL<1:0> bits, respectively. To clear an interrupt source, data must be written to, or read from, the SPIxBUF register to obtain the number of data to receive/transmit below the level specified by the SRXISEL<1:0> and STXISEL<1:0> bits. UART TX interrupt will be generated as soon as the UART module is enabled. Receive and transmit interrupts are controlled by the URXISEL<1:0> and UTXISEL<1:0> bits, respectively. To clear an interrupt source, data must be read from, or written to, the UxRXREG or UxTXREG registers to obtain the number of data to receive/transmit below the level specified by the URXISEL<1:0> and UTXISEL<1:0> bits. ADC All samples must be read from the result registers (ADC1BUFx) to clear the interrupt source. PMP To clear an interrupt source, read the Parallel Master Port Data Input/Output (PMDIN/PMDOUT) register.  2009-2019 Microchip Technology Inc. DS60001156K-page 423

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
