PORTD, TRISD and LATD

Registers

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., 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 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 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 10.6 “Parallel Slave

Port” for additional information on the Parallel Slave

Port (PSP).

Note:

PORTD is only available on PIC18F4X20

devices.

Note:

On a Power-on Reset, these pins are

configured as digital inputs.

Note:

When the enhanced PWM mode is used

with either dual or quad outputs, the PSP

functions of PORTD are automatically

disabled.
