16.9.5
Register Name:
Access Type:
Offset:
This register is used to disable PIO output drivers. If the pin is driven by the peripheral, this has no effect on the pin, but the
information is stored. The register is programmed as follows:
1 = Disables the PIO output on the corresponding pin.
0 = No effect.
16.9.6
Register Name:
Access Type:
Offset:
Reset Value:
This register shows the PIO pin control (output enable) status which is programmed in PIO_OER and PIO ODR. The
defined value is effective only if the pin is controlled by the PIO. The register reads as follows:
1 = The corresponding PIO is output on this line.
0 = The corresponding PIO is input on this line.
