This section describes the programming and debugging interface of the PIC32CX1012BZ24032 device. The following figure is added from the WBZ450 Curiosity Board design for reference. The pin Serial Wire Output (SWO) might not be required for general programming and debugging unless the program trace debugging is a requirement.
The following figure illustrates the pin-out of the Serial Wire Debug (SWD) interface required for interfacing with debuggers and/or programmers.Figure 2-11. Programming Pin-out Schematic Connection
Note: For a reliable operation in a noisy environment, adding a pull-up resistor of value 10 kΩ to the SWDCLK pin (PB8) is recommended. In addition, the RC filter on the NMCLR line must be placed very close to the MCLR pin of the PIC32CX1012BZ24032 device.
The following figure illustrates the schematic connections for the RC filter to be added on the NMCLR pin.
