10 k Ohm pulls up on MCLR so that the ICD can force 0, +5, +13 volts on this pin.
RB6 and RB7 used for PGC and PGD respectively between target and ICD2 module. Some of the requirements of the in-circuit debugger are as follows:
- The in-circuit debugger requires exclusive use of some hardware and software resources of the target.
- The target PIC-micro MCU must have a functioning clock and be running.
- The ICD2 can debug only when all the links in the system are fully functional.
