AUXILIARY HEADER PINOUTS
The two auxiliary headers, J17 and J18, allow for monitoring and debugging other pins
from the microcontroller as well as the CAN and LIN pins. Depending on which devel-
opment board is being used, the auxiliary headers have different pinouts. Table 2-1
maps out microcontroller pins to header pins for both development boards, the PIC18
Explorer Board and the Explorer 16 Board. Refer to Figure A-4 for the schematic of the
headers.
