10.0
All of the device pins (except V
OSCI/CLKI) are shared between the peripherals and
the parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
10.1
A parallel I/O port that shares a pin with a peripheral is,
in general, subservient to the peripheral. The periph-
eral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has ownership of the output data and control signals of
the I/O pin. The logic also prevents “loop through”, in
which a port’s digital output can drive the input of a
peripheral that shares the same pin.
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.

Output Multiplexers
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
may be read, but the output driver for the parallel port
bit will be disabled. If a peripheral is enabled, but the
peripheral is not actively driving a pin, that pin may be
driven by a port.
All port pins have three registers directly associated
with their operation as digital I/O. The Data Direction
register (TRIS) determines whether the pin is an input
or an output. If the data direction bit is a ‘1’, then the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the Output Latch register (LAT),
read the latch. Writes to the latch, write the latch.
Reads from the port (PORT), read the port pins, while
writes to the port pins, write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device will be
disabled. That means the corresponding LAT and
TRIS registers and the port pin will read as zeros.
When a pin is shared with another peripheral or func-
tion that is defined as an input only, it is regarded as a
dedicated port because there is no other competing
source of outputs.
