How to connect a PIC24H device to the ICD-U programmer/debug

PIC24Hnewbee · Guest

Hi,
I plan to use a PIC24H (PIC24HJ32GP304) in a new design. I have the ICD-U40 programmer/debugger hardware.
How do I connect the ICD to the PIC?
Is still right to use the RB6 (ICSP Clock), RB7 (ICSP Data) and the RB (for "special" debugging)?
I think NO: the PIC24H has more possibilities for ICSP data (RB0, RB5, RB10) and ICSP clock (RB1, RB6, RB11). This should be no problem. BUT: how do I connect the former RB3 pin?

Thank you very much for your help!

Hello,

as the PIC24 device manuals tell, any of the three pairs of debugging clock/data pins can be used:

PGC1/EMUC1 and PGD1/EMUD1
PGC2/EMUC2 and PGD2/EMUD2
PGC3/EMUC3 and PGD3/EMUD3

On some devices, the selection of a debugging pair may be incompatible with the usage of particular resources during debug. You should consult the manuals and also the errata sheets in this regard.

ICD-U40 "adavanced debugging pin" is connected to a software UART and thus generally selectable. I think, you can use any pin for this purpose. Hopefully, ICD-U40 software is fully supporting your PIC24H device.
