Compare Channel 0 Interrupt Flag
The Compare Interrupt flag (CMPn) is set on a compare match on the corresponding compare channel.
For all modes of operation, the CMPn flag will be set when a compare match occurs between the Count register (TCAn.CNT) and the corresponding Compare register (TCAn.CMPn). The CMPn flag is not cleared automatically, only by writing a ‘1’ to its bit location.
Overflow/Underflow Interrupt Flag
This flag is set either on a TOP (overflow) or BOTTOM (underflow) condition, depending on the WGMODE setting. The OVF flag is not cleared automatically, only by writing a ‘1’ to its bit location.
