3.3 In-Circuit Serial Programming (ICSP) Header (J206)

The ICSP header (J206) is a 6-pin staggered header. It allows in-circuit emulation and debugging using Microchip's in-circuit emulator tools, and it allows direct programming of the WFI32E03 module. The ICSP header supports external debuggers, such as MPLAB ICD 5, MPLAB PICkit 4, MPLAB PICkit 5 and MPLAB Snap. Use the standard ICSP header to connect an MPLAB programmer or debugger to the PIC32 WFI32 2.0 Curiosity Board. The following figure illustrates the connection between the ICSP header, external debuggers and the PIC32 WFI32 2.0 Curiosity Board.

Note:
  1. For more details on the WFI32E03 pins, refer to the PIC32MZ W1 MCU and WFI32 Module with Wi-Fi® and Hardware-Based Security Accelerator Data Sheet (DS70005425).
  2. Use an external debugger such as MPLAB ICD 5, MPLAB PICkit 4, MPLAB PICkit 5 or MPLAB Snap for the best programming and debugging experience.
