⢠Bit 1 â OCFnA: Output Compare Flag n A
The OCFnA bit is set when a Compare Match occurs between the Timer/Countern and the data
in OCRnA â Output Compare Registern A. OCFnA is cleared by hardware when executing the
corresponding interrupt handling vector. Alternatively, OCFnA is cleared by writing a logic one to
the flag. When the I-bit in SREG, OCIEnA (Timer/Countern Compare Match Interrupt Enable),
and OCFnA are set, the Timer/Countern Compare Match Interrupt is executed.
⢠Bit 0 â TOVn: Timer/Countern Overflow Flag
The bit TOVn is set when an overflow occurs in Timer/Countern. TOVn is cleared by hardware
when executing the corresponding interrupt handling vector. Alternatively, TOVn is cleared by
writing a logic one to the flag. When the SREG I-bit, TOIEn (Timer/Countern Overflow Interrupt
Enable), and TOVn are set, the Timer/Countern Overflow interrupt is executed.
