If the data direction bits of the associated I/O pins are set to 1, a read
returns the value of the port register, otherwise the value at the pins is
read.
The PWM function takes precedence over the general purpose I/O
function if the associated PWM channel is enabled. While channels 6–0
are output only if the respective channel is enabled, channel 7 can be
PWM output or input if the shutdown feature is enabled. See Pulse Width
Modulator (PWM8B8C) section on page 249 for details.

This register always reads back the status of the associated pins. This
can be also used to detect overload or short circuit conditions on output
pins.
