Note:
  1. The remappable peripherals can use all GPIOs (RPAn, RPBn, RPCn, RPDn and RPEn) via PPS.
  2. All GPIOs (RPAn, RPBn, RPCn, RPDn, and RPEn) can be used for I/O Change Notification (IOCAn, IOCBn, IOCCn, IOCDn and IOCEn).
  3. Connect the metal paddle at the bottom of the device to the system ground.
  4. If not using SOSC, use this pin as an input-only pin.
  5. JTAG is the default functionality on these pins. It is recommended to write 0 to the CFGCON0.JTAGEN register during application initialization to use these pins for regular GPIO functionality.
  6. A pull-up resistor (10K) on the SWCLK pin is critical for reliable operation.
  7. For more details on power supply pin connections and the filtering components, refer to the Design Package available on the product page.
  8. Provide filtered version of main supply input.
  9. Connect a 100 nF decoupling capacitor to this pin.
  10. These I/O pins are 5.5V tolerant:
    • NMCLR, PA0, PA1, PA2, PA4, PA5, PA6, PA7, PA8, PA10, PA13, PA15, PB3, PB12, PB13, PC0, PC1, PC8, PC9, PC10, PC11, PD0, PD1, PE0, PE1, PE2, PE3 and PE4.
    • All other I/O pins are 3.3V tolerant.
  11. The following is the grouping of the pins based on their drive strength:
    • 4x drive strength: PE2, PC8, PE3, PC10, PB8, PB10, PD2, PE6, PE5, PE4, PC11, PB6, PA3, PB2, PB4, PD3, PD5, PB3, PA15, PB7, PD4, PB15, PB14,PB0,PB1, PD6, PD7, PC7 and PB5.
    • 8x drive strength: PA0, PA1, PA2, PA4, PA5, PA6, PA7, PA8, PA9. PA10, PA13, PA14, PB12, PB13, PB9, PE0 and PB11.
    • 12x drive strength: PD0, PD1, PC9, PC1, PC0 and PE1.
