• Bit 0– TOV0: Timer/Counter0 Overflow Flag
The bit TOV0 is set when an overflow occurs in timer/counter 0. TOV0 is cleared by hardware
when executing the corresponding interrupt handling vector. Alternatively, TOV0 is cleared by
writing a logical one to the flag. When the SREG I-bit, TOIE0 (timer/counter 0 overflow inter-
rupt enable), and TOV0 are set, the timer/counter 0 overflow interrupt is executed.
The setting of this flag is dependent of the WGM02:0 bit setting. See
Table 13-8 on page 86
and
“Waveform Generation Mode Bit Description” on page
86.
