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 (ST) 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. Figure 10-1 shows
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 it 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 it 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 and one register asso-
ciated with their operation as analog input. The Data
Direction register (TRISx) 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 reg-
ister (LATx), read the latch; writes to the latch, write the
latch. Reads from the port (PORTx), read the port pins;
writes to the port pins, write to 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 LATx and
TRISx 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 inputs.
