TIFR – Timer/Counter Interrupt Flag Register
• Bit 0 – TOV0: Timer/Counter0 Overflow Flag
The bit TOV0 is set (one) when an overflow occurs in Timer/Counter0. TOV0 is cleared by hard-
ware when executing the corresponding interrupt Handling Vector. Alternatively, TOV0 is
cleared by writing a logic one to the flag. When the SREG I-bit, TOIE0 (Timer/Counter0 Overflow
Interrupt Enable), and TOV0 are set (one), the Timer/Counter0 Overflow interrupt is executed.
