ATmega161(L)
• Bit 5
When the OCIE1B bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter1 CompareB Match interrupt is enabled. The corresponding interrupt (at
Vector $010) is executed if a Compare B Match in Timer/Counter1 occurs, i.e., when the
OCF1B bit is set in the Timer/Counter Interrupt Flag Register (TIFR).
• Bit 4
When the TOIE2 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter2 Overflow interrupt is enabled. The corresponding interrupt (at Vector
$00a) is executed if an overflow in Timer/Counter2 occurs, i.e., when the TOV2 bit is set
in the Timer/Counter Interrupt Flag Register (TIFR).
• Bit 3
When the TICIE1 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter1 Input Capture Event Interrupt is enabled. The corresponding interrupt
(at Vector $00C) is executed if a capture-triggering event occurs on pin 31, ICP, i.e.,
when the ICF1 bit is set in the Timer/Counter Interrupt Flag Register (TIFR).
• Bit 2
When the OCIE2 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter2 Compare Match interrupt is enabled. The corresponding interrupt (at
Vector $008) is executed if a Compare2 match in Timer/Counter2 occurs, i.e., when the
OCF2 bit is set in the Timer/Counter Interrupt Flag Register (TIFR).
• Bit 1
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
$016) is executed if an overflow in Timer/Counter0 occurs, i.e., when the TOV0 bit is set
in the Timer/Counter Interrupt Flag Register (TIFR).
• Bit 0
When the OCIE0 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter0 Compare Match interrupt is enabled. The corresponding interrupt (at
Vector $014) is executed if a Compare 0 Match in Timer/Counter0 occurs, i.e., when the
OCF0 bit is set in the Timer/Counter Interrupt Flag Register (TIFR).
