10.0
Depending on the device selected and features
enabled, there are up to nine ports available. Some
pins of the I/O ports are multiplexed with an alternate
function from the peripheral features on the device. In
general, when a peripheral is enabled, that pin may not
be used as a general purpose I/O pin.
Each port has three registers for its operation. These
registers are:
• TRIS register (data direction register)
• PORT register (reads the levels on the pins of the
• LAT register (output latch)
The
read-modify-write operations on the value that the I/O
pins are driving.
A simplified model of a generic I/O port, without the
interfaces to other peripherals, is shown in Figure 10-1.

Preliminary
for
10.1
When developing an application, the capabilities of the
port pins must be considered. Outputs on some pins
have higher output drive strength than others. Similarly,
some pins can tolerate higher than V
10.1.1
The output pin drive strengths vary for groups of pins
intended to meet the needs for a variety of applications.
PORTB and PORTC are designed to drive higher
loads, such as LEDs. The external memory interface
ports (PORTD, PORTE and PORTJ) are designed to
drive medium loads. All other ports are designed for
small loads, typically indication only. Table 10-1 sum-
marizes the output capabilities. Refer to Section 26.0
“Electrical Characteristics” for more details.
