PIO Output Data Status Register
Register Name: PIO_ODSR
Access Type:
Reset Value:
Offset:
This register shows the output data status which is programmed in PIO_SODR or PIO_CODR. The defined value is effec-
tive only if the pin is controlled by the PIO Controller and only if the pin is defined as an output.
1 = The output data for the corresponding line is programmed to 1.
0 = The output data for the corresponding line is programmed to 0.
PIO Pin Data Status Register
Register Name: PIO_PDSR
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.
