1.3.1 PGECx and PGEDx Pin Pairs
All devices in the dsPIC33CK256MC006 family have three separate pairs of programming pins, labeled as PGEC1/PGED1, PGEC2/PGED2 and PGEC3/PGED3. Any one of these pin pairs may be used for device programming by either ICSP or Enhanced ICSP. Unlike voltage supply and ground pins, it is not necessary to connect all three pin pairs to program the device. However, the programming method must use both pins of the same pair.
