PIO Output Status Register
Register Name: PIO_OSR
Access Type:
Reset Value:
Offset:
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.
