PORTD is an 8-bit port with Schmitt Trigger input buffers.
Each pin is individually configured as an input or output.
PORTD is only available on the PIC16F914 and
PIC16F917.

bit 7-0
Analog lines that carry LCD signals
(i.e., SEGx, COMy, where x and y are seg-
ment and common identifiers) are shown
as direct connections to the device pins.
The signals are outputs from the LCD
module and may be tri-stated, depending
on the configuration of the LCD module.
