Bit 5 – ICIE4: Timer/Counter 4, Input Capture Interrupt Enable

Timer/Counter 4, Input Capture Interrupt Enable

When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally enabled), the Timer/Counter 4 Input Capture interrupt is enabled. The corresponding Interrupt Vector is executed when the ICF4 Flag, located in TIFR4, is set.

Bit 2 – OCIE4B: Timer/Counter 4, Output Compare B Match Interrupt Enable

Timer/Counter 4, Output Compare B Match Interrupt Enable

When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally enabled), the Timer/Counter n Output Compare B Match interrupt is enabled. The corresponding Interrupt Vector is executed when the OCF4B Flag, located in TIFR4, is set.

Bit 1 – OCIE4A: Timer/Counter 4, Output Compare A Match Interrupt Enable

Timer/Counter 4, Output Compare A Match Interrupt Enable

When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally enabled), the Timer/Counter n Output Compare A Match interrupt is enabled. The corresponding Interrupt Vector is executed when the OCF4A Flag, located in TIFR4, is set.

Bit 0 – TOIE4: Timer/Counter 4, Overflow Interrupt Enable

Timer/Counter 4, Overflow Interrupt Enable

When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally enabled), the Timer/Counter 4 Overflow interrupt is enabled. The corresponding Interrupt Vector is executed when the TOV Flag, located in TIFR4, is set.
