19.6.4 Output Pins

The SUPC can drive two backup pin outputs. By writing a '1' to the corresponding Output Enable bit in the Backup Output Control register (BKOUT.EN), the OUTx pin is driven by the SUPC.

The OUTx pin can be set by writing a '1' to the corresponding Set Output bit in the Backup Output Control register (BKOUT.SETx).

The OUTx pin can be cleared by writing a '1' to the corresponding CLR bit (BKOUT.CLRx).

If a RTC Toggle Enable bit is written to '1' (BKOUT.RTCTGLx), the corresponding OUTx pin will toggle when an RTC event occurs.

The BKIN.BKINx bit reflects the state of corresponding OUTx pins.
