PIC16F917/916/914/913
3.5
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.

TRISD – PORTD TRI-STATE REGISTER (ADDRESS: 88h)
RD<7:0>: PORTD I/O Pin bits
1 = Port pin is >V
0 = Port pin is <V
TRISD<7:0>: PORTD Tri-State Control bits
1 = PORTD pin configured as an input (tri-stated)
0 = PORTD pin configured as an output
