Microchip Technology 

PIC16F913/914/916/917/946

3.8 PORTF and TRISF Registers

PORTF is an 8-bit port with Schmitt Trigger input buff-

ers. RF<7:0> are individually configured as inputs or

outputs, depending on the state of the port direction.

The port bits are also multiplexed with LCD segment

functions. PORTF is available on the PIC16F946 only.

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-0

RF<7:0>: PORTF I/O Pin bits

1 = Port pin is >VIH min.

0 = Port pin is <VIL max.
