Bit 5 – ICIE1 Timer/Counter 1,
Input Capture Interrupt Enable
When this bit is
written to '1', and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter 1 Input Capture interrupt is enabled. The corresponding
Interrupt Vector is executed when the ICF1 Flag, located in TIFR1, is
set.
Bit 2 – OCIE1B Timer/Counter 1,
Output Compare B Match Interrupt Enable
When this bit is
written to '1', and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter 1 Output Compare B Match interrupt is enabled. The
corresponding Interrupt Vector is executed when the OCF1B Flag, located in TIFR1, is
set.
Bit 1 – OCIE1A Timer/Counter 1,
Output Compare A Match Interrupt Enable
When this bit is
written to '1', and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter 1 Output Compare A Match interrupt is enabled. The
corresponding Interrupt Vector is executed when the OCF1A Flag, located in TIFR1, is
set.
Bit 0 – TOIE1 Timer/Counter 1,
Overflow Interrupt Enable
When this bit is
written to '1', and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter 1 Overflow interrupt is enabled. The corresponding
Interrupt Vector is executed when the TOV Flag, located in TIFR1, is
set.
