vector $003) is executed if a compare match A in Timer/Counter1 occurs, i.e., when the
OCF1A bit is set (one) in the Timer/Counter Interrupt Flag Register (TIFR).
Bit 5..3 – Res: Reserved Bits
These bits are reserved bits in the ATtiny15L and always read as zero.
Bit 2 – TOIE1: Timer/Counter1 Overflow Interrupt Enable
When the TOIE1 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter1 Overflow interrupt is enabled. The corresponding interrupt (at vector
$004) is executed if an overflow in Timer/Counter1 occurs, i.e., when the TOV1 bit is set
(one) in the Timer/Counter Interrupt Flag Register (TIFR).
Bit 1 – TOIE0: Timer/Counter0 Overflow Interrupt Enable
When the TOIE0 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter0 Overflow interrupt is enabled. The corresponding interrupt (at vector
$005) is executed if an overflow in Timer/Counter0 occurs, i.e., when the TOV0 bit is set
(one) in the Timer/Counter Interrupt Flag Register (TIFR).
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the ATtiny15L and always reads as zero.
The Timer/Counter Interrupt
Flag Register – TIFR
Bit 7 – Res: Reserved Bit
This bit is a reserved bit in the ATtiny15L and always reads as zero.
Bit 6 – OCF1A: Output Compare Flag 1A
The OCF1A bit is set (one) when compare match occurs between Timer/Counter1 and
the data value in OCR1A (Output Compare Register 1A). OCF1A is cleared by hard-
ware when executing the corresponding interrupt handling vector. Alternatively, OCF1A
is cleared by writing a logical “1” to the flag. When the I-bit in SREG, OCIE1A, and
OCF1A are set (one), the Timer/Counter1 compare match A interrupt is executed.
Bits 5..3 – Res: Reserved bits
These bits are reserved bits in the ATtiny15L and always read as zero.
Bit 2 – TOV1: Timer/Counter1 Overflow Flag
The bit TOV1 is set (one) when an overflow occurs in Timer/Counter1. TOV1 is cleared
by hardware when executing the corresponding interrupt handling vector. Alternatively,
TOV1 is cleared by writing a logical “1” to the flag. When the SREG I-bit, TOIE1

Timer/Counter1 Overflow Interrupt is executed.
