14.6.13
Register Name:
Access Type:
Reset Value:
Offset:
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.
14.6.14
Register Name:
Access Type:
Offset:
This register is used to enable PIO interrupts on the corresponding pin. It has effect whether PIO is enabled or not.
1 = Enables an interrupt when a change of logic level is detected on the corresponding pin.
0 = No effect.
