ICSP Connection

PIC24EP256GU814 has more than one pair of PGECx and PGEDx pins. You can use any pair, but you must use them as a pair. For example, if PGEC2 is used for ICSPCLK, then ICSPDAT must be connected to PGED2.

All VSS and VDD pins must be connected. Even if one of these pins is not connected, programming may fail.

PIC24EP256GU814 is more sensitive to cross-talk between PGEC and PGED lines than other PIC devices. This may lead to programming failures, such as inability to connect or various verification failures. One of the methods to improve connectivity is to connect a small 20pF capacitor between PGEC line and VSS as close to the chip as possible. A bigger capacitor may be used, however you will have to decrease ICSP communication speed.

Programming Benchmarks for NSDSP-1 and NSDSP-2

We have measured time necessary to program and verify PIC24EP256GU814 with NSDSP-1 or NSDSP-2 (both yeild the same speed).

The measurements reflect the time necessary to program/verify the entire chip, including all user programmable memory areas.

Debugging

NSDSP firmware contains all the necessary provisions for debugging PIC24EP256GU814 and may be debugged when debugging software becomes available.

PIC24EP256GU814 uses unordered halting, has 8 hardware breakpoints.

Debugging does not consume resources in the user space.
