The
devices are designed to support an alternate
programming input: the dedicated ICSP/ICD port. The
primary purpose of this port is to provide an alternate
In-Circuit Debugging (ICD) option and free the pins
(RB6, RB7 and MCLR) that would normally be used for
debugging the application. In conjunction with ICD
capability, however, the dedicated ICSP/ICD port also
provides an alternate port for ICSP.
Setting the ICPRT Configuration bit enables the
dedicated ICSP/ICD port. The dedicated ICSP/ICD
port functions the same as the default ICSP/ICD port;
however, alternate pins are used instead of the default
pins.
pins for ICSP purposes:
The dedicated ICSP/ICD port is an alternate port. Thus,
ICSP is still available through the default port even
though the ICPRT Configuration bit is set. When the

The ICPRT Configuration bit can only be
programmed through the default ICSP
port. Chip Erase functions through the
dedicated ICSP/ICD port do not affect this
bit.
When the ICPRT Configuration bit is set
