In general, when a peripheral is enabled on a port pin,
that pin cannot be used as a general purpose output.
However, the pin can still be read.
Each port has three standard registers for its operation.
These registers are:
• TRISx registers (data direction)
• PORTx registers (reads the levels on the pins of
• LATx registers (output latch)
Some ports may have one or more of the following
additional registers. These registers are:
• ANSELx (analog select)
• WPUx (weak pull-up)
TABLE 12-1:
The Data Latch (LATA register) is useful for
read-modify-write operations on the value that the I/O
pins are driving.
A write operation to the LATA register has the same
affect as a write to the corresponding PORTA register.
A read of the LATA register reads of the values held in
the I/O PORT latches, while a read of the PORTA
register reads the actual I/O pin value.
The port has analog functions and has an ANSELA
register which can disable the digital input and save
power. A simplified model of a generic I/O port, without
the interfaces to other peripherals, is shown in
