Timer/Counter Interrupt Flag
Register – TIFR
2486M–AVR–12/03
• Bit 0 – TOV0: Timer/Counter0 Overflow Flag
The bit TOV0 is set (one) when an overflow occurs in Timer/Counter0. TOV0 is cleared
by hardware 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/Counter 0 Overflow Inter rupt Enable), and TOV0 are set (one), the
Timer/Counter0 Overflow interrupt is executed.
