2.4.6 PICkit Serial or In-Circuit Serial Programming (ICSP) Interface
(Header J1)
Figure 2-8 shows the interface connection of the J1 Header. The V
DD
and V
SS
signals
are connected to the appropriate power or ground plane. The other four signals are
open and can be easily jumpered to any of the 10 P1 through P10 connection points.
The top layer silk screen indicates the common PICkit Serial signal names, while the
bottom layer silk screen indicates the ICSP signal names.
