PIC18F66K80 FAMILY
11.5
PORTD is an 8-bit wide, bidirectional port. The
are TRISD and LATD.
All pins on PORTD are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
Each of the PORTD pins has a weak internal pull-up. A
single control bit can turn off all the pull-ups. This is
performed by setting bit, RDPU (PADCFG1<7>). The
weak pull-up is automatically turned off when the port
pin is configured as an output. The pull-ups are
disabled on all device Resets.

Note:
PORTD, TRISD and
LATD Registers
PORTD is unavailable on 28-pin devices.
These pins are configured as digital inputs
on any device Reset.
Preliminary
PORTD can also be configured as an 8-bit wide micro-
processor port (Parallel Slave Port) by setting control
bit, PSPMODE (PSPCON<4>). In this mode, the input
buffers are ST. For additional information, see
Section 11.9 “Parallel Slave Port”
RD3 has a CTMU functionality.
