ATtiny26(L)
• Bit 2 – TOV1: Timer/Counter1 Overflow Flag
The bit TOV1 is set (one) when an overflow occurs in Timer/Counter1. TOV1 is cleared by hard-
ware when executing the corresponding interrupt handling vector. Alternatively, TOV1 is
cleared, after synchronization clock cycle, by writing a logical one to the flag. When the SREG I-
bit, and TOIE1 (Timer/Counter1 Overflow Interrupt Enable), and TOV1 are set (one), the
Timer/Counter1 Overflow interrupt is executed.
• Bit 1 – 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 logical one to the flag. When the SREG I-bit, and TOIE0 (Timer/Counter0 Overflow
Interrupt Enable), and TOV0 are set (one), the Timer/Counter0 Overflow interrupt is executed.
• Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the ATtiny26(L) and always reads as zero.
