Bit 15 – OVF Overflow
This flag is cleared by writing a '1' 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 '1'.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit clears the Overflow interrupt flag.
Bits 8, 9 – CMPn Compare n Interrupt Enable [n = 1..0]
| Value | Description |
|---|---|
| 0 | The Compare n interrupt is disabled. |
| 1 | The Compare n interrupt is enabled. |
Bits 0, 1, 2, 3, 4, 5, 6, 7 – PERn Periodic Interval n [n = 7..0]
This flag is cleared by writing a '1' to the flag.
This flag is set on the 0-to-1 transition of prescaler bit [n+2], and an interrupt request will be generated if INTENCLR/SET.PERx is one.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit clears the Periodic Interval n interrupt flag.
