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 if INTENCLR/SET.OVF is one.
be generated if INTENCLR/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.
except when caused by Enable or software Reset, and an interrupt request will be generated if INTEN-

Writing a zero to this bit has no effect.
Writing a one to this bit clears the Synchronization Ready interrupt flag.
z
Bits 5:1 – Reserved
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.

Bit 0 – ALARM0: Alarm 0
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 a match with ALARM0 condition occurs, and an interrupt
request will be generated if INTENCLR/SET.ALARM0 is also one.
