Bit 3 – XOSC32KSW XOSC32K 32.768kHz Clock Switch

Note: This bit is set by hardware if a 32.768kHz clock fail detect occurs and clock fail detect is enabled, (i.e. CFDCTRL.CFDEN =1 and INTFLAG.XOSC32KFAIL=1 or STATUS.XOSC32KFAIL=1).
ValueDescription
0XOSC32K is not switched and the clock source is provided by the external 32.768kHz oscillator source.
1XOSC32K is switched to the internal OSCULP32K oscillator clock. Both 32.768kHz and 1.024kHz outputs of the XOSC32K are replaced by the respective OSCULP32K 32 kHz and 1 kHz outputs to the respective logic modules.

Bit 2 – XOSC32KFAIL XOSC32K 32.768kHz Clock Failure Detect

Note: This bit is set by hardware if a 32.768kHz clock fail detect occurs and clock fail detect is enabled, (i.e. CFDCTRL.CFDEN =1 and INTFLAG.XOSC32KFAIL=1).
ValueDescription
0No XOSC32K 32.768kHz clock fail detection.
1XOSC32K 32.768kHz external crystal/clock fail detect. Hardware clock switch will be initiated to OSCULP32K oscillator clocks.

Bit 0 – XOSC32KRDY XOSC32K Ready

Note: This bit is set and cleared by hardware based on the status of the of the active XOSC32K 32.768kHz clock source.
ValueDescription
0XOSC32K is not ready.
1XOSC32K is stable and ready to be used as a clock source.
