PORTC is an 8-bit bidirectional port. PORTC is
multiplexed with several peripheral functions. PORTC
pins have Schmitt Trigger input buffers.
All PORTC pins have latch bits (PORTC register).
They, when written, will modify the contents of the
PORTC latch; thus, modifying the value driven out on
a pin if the corresponding TRISC bit is configured for
output.

Analog lines that carry LCD signals
(i.e., SEGx, VLCDy, where x and y are
segment and LCD bias voltage 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.
