Bit 7 – OVF: Overflow
This flag is cleared by writing a one to the flag.
This flag is cleared by writing a one to the flag.
This flag is set on the next CLK_RTC_CNT cycle after an overflow condition occurs, and an interrupt request will
be generated ifINTENCLR/SET.OVF is one.

Writing a zero to this bit has no effect.
Writing a one to this bit clears the Overflow interrupt flag.
z
Bit 6 – SYNCRDY: Synchronization Ready
This flag is cleared by writing a one to the flag.
This flag is cleared by writing a one to the flag.
This flag is set on a 1-to-0 transition of the Synchronization Busy bit in the Status register (STATUS.SYNCBUSY),
except when caused by Enable or software Reset, and an interrupt request will be generated if INTEN-
CLR/SET.SYNCRDY is one.

These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to
zero when this register is written. These bits will always return zero when read.
