Description
PORTD is a bidirectional I/O port or a Parallel Slave Port
(PSP) for interfacing to a microprocessor port. These pins
have TTL input buffers when PSP module is enabled.

Legend:
TTL = TTL compatible input
ST = Schmitt Trigger input with CMOS levels
O = Output
OD = Open-drain (no diode to VDD)
CMOS = CMOS compatible input or output
I
= Input
P = Power
Note 1: Default assignment for CCP2 when CCP2MX (CONFIG3H<0>) is set.
2: Alternate assignment for CCP2 when CCP2MX is cleared.
