PIO Output Enable Register
Register Name: PIO_OER
Access Type:
Offset:
This register is used to enable PIO output drivers. If the pin is driven by a peripheral, this has no effect on the pin, but the
information is stored. The register is programmed as follows:
1 = Enables the PIO output on the corresponding pin.
0 = No effect.
PIO Output Disable Register
Register Name: PIO_ODR
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.
