I/O PORTS
This data sheet summarizes the features of
Note:
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the I/O
Ports, refer to the “PIC24F Family Refer-
ence Manual”, Section 12. “I/O Ports with
Peripheral Pin Select (PPS)” (DS39711).
Note that the PIC24F16KA102 family
devices do not support Peripheral Pin
Select features.
All of the device pins (except V
and V
DD
between the peripherals and the parallel I/O ports. All
I/O input ports feature Schmitt Trigger inputs for
improved noise immunity.
11.1
Parallel I/O (PIO) Ports
A parallel I/O port that shares a pin with a peripheral is,
in general, subservient to the peripheral. The
peripheral’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 11-1
displays how ports are shared with other peripherals
and the associated I/O pin to which they are connected.

PIC24F16KA102 FAMILY
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 (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 Data Latch register (LATx), read
) are shared
SS
the latch. Writes to the latch, write the latch. Reads
from the port (PORTx), 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 LATx and
TRISx registers and the port pin will read as zeros.
When a pin is shared with another peripheral or
function that is defined as an input only, it is
nevertheless regarded as a dedicated port because
there is no other competing source of outputs.
The I/O pins retain their state during Deep
Note:
Sleep. They will retain this state at
wake-up until the software restore bit
(RELEASE) is cleared.
