PICkit SERIAL PIN ASSIGNMENTS
The PICkit Serial connection header is designed to allow a PICkit serial to be con-
nected to the controller board. The communication is done using the I 2 C? standard, in
which case the PICkit Serial Analyzer is the master device and the board acts as a
slave I 2 C device.
The pin assignments are shown in Figure 5-1.
