5.0. ICD Connector
The ICD connector enables communication between the microcontroller and an external ICD debugger/programmer (ICD2 or ICD3)
from Microchip. Jumpers J1 and J2 are used for selecting the pin to be fed with programming signals. For the programming signal
to be sent to the microcontroller, it is necessary to place both jumpers in the same position, as shown in Figure 5-2. Either RA0 and
RA1 or RB0 and RB1 or RB6 and RB7 microcontroller pins can be fed with this signal. The position of jumpers J1 and J2 depends on
the microcontroller provided on the board. When the PIC24F16KA102 microcontroller is programmed by means of the external ICD
programmer, jumpers J1 and J2 should be placed in the RB0 and RB1 positions, respectively. In case some other microcontroller is
used, it is necessary to check which microcontroller pins can be fed with the programming signal.
