11.4
PORTD is an 8-bit wide, bidirectional port. The
corresponding 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 high-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).
The Data Latch register (LATD) is also memory
mapped. Read-modify-write operations on the LATD
register read and write the latched output value for
PORTD.
All pins on PORTD are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.

Note:
PORTD, TRISD and LATD
Registers
PORTD is only available on PIC18F4331/
4431 devices.
On a Power-on Reset, these pins are
configured as digital inputs.
PORTD includes PWM<7:6> complementary fourth
channel PWM outputs. PWM4 is the complementary
output of PWM5 (the third channel), which is multi-
plexed with the RB5 pin. This output can be used as the
alternate output using the PWM4MX Configuration bit
in CONFIG3H when the Single-Supply Programming
pin (PGM) is used on RB5.
RD1, RD2 and RD3 can be used as the alternate out-
put for SDO, SDI/SDA and SCK/SCL using the SSPMX
Configuration bit in CONFIG3H.
RD4 an be used as the alternate output for FLTA using
the FLTAMX Configuration bit in CONFIG3H.
