8.4
PORTD is an 8-bit wide, bi-directional port. The corre-
sponding Data Direction register is TRISD. Setting a
TRISD bit (=1) will make the corresponding PORTD pin
an input (i.e., put the corresponding output driver in a
hi-impedance mode). Clearing a TRISD bit (=0) will
make the corresponding PORTD pin an output (i.e., put
the contents of the output latch on the selected pin).
Read-modify-write operations on the LATD register
reads and writes the latched output value for PORTD.
PORTD is an 8-bit port with Schmitt Trigger input buff-
ers. Each pin is individually configurable as an input or
output.
PORTD can be configured as an 8-bit wide micro-
processor port (parallel slave port), by setting control
bit PSPMODE (PSPCON register). In this mode, the
input buffers are TTL. See Section 9.0 for additional
information on the Parallel Slave Port (PSP).
