PIC32MX5XX/6XX/7XX
28.4 Programming and Diagnostics
PIC32MX5XX/6XX/7XX devices provide a complete
range of programming and diagnostic features that can
increase the flexibility of any application using them.
These features allow system designers to include:
⢠Simplified field programmability using two-wire
In-Circuit Serial Programming⢠(ICSPâ¢)
interfaces
⢠Debugging using ICSP
⢠Programming and debugging capabilities using
the EJTAG extension of JTAG
⢠JTAG boundary scan testing for device and board
diagnostics
PIC32 devices incorporate two programming and diag-
nostic modules, and a trace controller, that provide a
range of functions to the application developer.
