Compare Channel 0 Interrupt Flag
The Compare Interrupt (CMPn) flag 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 (TCAn.CNT) register and the corresponding Compare n
(TCAn.CMPn) register. The CMPn flag is not cleared automatically. It will be
cleared 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. It will be cleared only by writing a ‘1
’ to its
bit location.
