Timer/Counter Interrupt Flag

• Bits 7..2 - Res: Reserved Bits
These bits are reserved bits in the ATtiny11/12 and always read as zero.
• Bit 1 - 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 logical 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.
• Bit 0 - Res: Reserved bit
