OCFnB is automatically cleared when the Output Compare Match B Interrupt Vector is
executed. Alternatively, OCFnB can be cleared by writing a logic one to its bit location.
• Bit 1 – OCFnA: Output Compare A Match Flag
This flag is set in the timer clock cycle after the counter (TCNTn) value matches the Out-
put Compare Register A (OCRnA).
Note that a Forced Output Compare (FOCnA) strobe will not set the OCFnA flag.
OCFnA is automatically cleared when the Output Compare Match A Interrupt Vector is
executed. Alternatively, OCFnA can be cleared by writing a logic one to its bit location.
• Bit 0 – TOVn: Timer/Counter Overflow Flag
The setting of this flag is dependent of the WGMn3:0 bits setting. In Normal and CTC
modes, the TOVn flag is set when the timer overflows. Refer to Table 63 on page 133
for the TOVn flag behavior when using another WGMn3:0 bit setting.
TOVn is automatically cleared when the Timer/Countern Overflow Interrupt Vector is
executed. Alternatively, TOVn can be cleared by writing a logic one to its bit location.
