10.5
PORTD is an 8-bit wide, bidirectional port. The corre-
sponding data direction register is TRISD. Setting a
TRISD bit (= 1) will make the corresponding PORTD
pin an input (i.e., disable the output driver). Clearing a
TRISD bit (= 0) will make the corresponding PORTD
pin an output (i.e., enable the output driver and 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 Trig-
ger input buffers. Each pin is individually configurable
as an input or output.
Three of the PORTD pins are multiplexed with outputs
P1B, P1C and P1D of the enhanced CCP module. The
operation of these additional PWM output pins is
covered in greater detail in Section 16.0 “Enhanced
Capture/Compare/PWM (ECCP) Module”.

PORTD, TRISD and LATD
Registers
PORTD is only available on 40/44-pin
devices.
On a Power-on Reset, these pins are
configured as digital inputs.
PORTD can also be configured as an 8-bit wide micro-
processor port (Parallel Slave Port) by setting control
bit, PSPMODE (TRISE<4>). In this mode, the input
buffers are TTL. See Section 10.9 “Parallel Slave
Port” for additional information on the Parallel Slave
Port (PSP).

When the enhanced PWM mode is used
with either dual or quad outputs, the PSP
functions of PORTD are automatically
disabled.
