Description
PORTD is a bidirectional I/O port or a Streaming
Parallel Port (SPP). PORTD can be software
programmed for internal weak pull-ups on all inputs.
These pins have TTL input buffers when the SPP
module is enabled.

Note 1: Alternate assignment for CCP2 when CCP2MX Configuration bit is cleared.
2: Default assignment for CCP2 when CCP2MX Configuration bit is set.
3: These pins are No Connect unless the ICPRT Configuration bit is set. For NC/ICPORTS, the pin is No
Connect unless ICPRT is set and the DEBUG Configuration bit is cleared.
