34.7 Programming and Debugging Ports

For programming and/or debugging PIC32C, the device must be connected using the Serial Wire Debug (SWD) interface. Currently the SWD interface is supported by several Microchip and third party programmers and debuggers.

Note: A pull-up resistor on the SWCLK pin is critical for reliable operations.
