1 = The output data for the corresponding line is programmed to 1.
0 = The output data for the corresponding line is programmed to 0.

This register shows the state of the physical pin of the chip. The pin values are always valid regardless of whether the pins
are enabled as PIO, peripheral, input or output. The register reads as follows:
1 = The corresponding pin is at logic 1.
0 = The corresponding pin is at logic 0.
