2.3.2.6
2.3.2.6.1
Read: Anytime.
Write: Anytime.
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.
2.3.2.6.2
Read: Anytime.
Write: Never, writes to this register have no effect.
This register always reads back the status of the associated pins. This can be used to detect overload or
short circuit conditions on output pins.
