ATmega323(L)

In overflow PWM mode, the table above is only valid for OCR1X = TOP.

In PWM mode, the Timer Overflow Flag1, TOV1, is set when the counter advances from

$0000. In overflow PWM mode, the Timer Overflow flag is set as in normal

Timer/Counter mode. Timer Overflow Interrupt1 operates exactly as in normal

Timer/Counter mode, i.e. it is executed when TOV1 is set provided that Timer Overflow

Interrupt1 and global interrupts are enabled. This also applies to the Timer Output

Compare1 flags and interrupts.
