Bit 7 –  Reserved Bit

This bit is reserved and read as ‘0’.

Bit 6 –  Reserved Bit

This bit is reserved and read as ‘0’.

Bit 5 –  Reserved Bit

This bit is reserved and read as ‘0’.

Bit 4 –  Reserved Bit

This bit is reserved and read as ‘0’.

Bit 3 –  Reserved Bit

This bit is reserved and read as ‘0’.

Bit 2 – T3CPIM Timer3 Capture Interrupt Mask

If this bit is written to ‘1’, and the I flag in SREG is set (interrupts globally enabled), the Timer3 input capture interrupt is enabled. The corresponding interrupt vector is executed when the T3ICF flag, located in T3IFR, is set.

Bit 1 – T3CIM Timer3 Compare Interrupt Mask

If the T3CIM bit is written to ‘1’ and the I bit in SREG is set, the Timer3 compare match interrupt is enabled. The corresponding interrupt is executed if a compare match in Timer3 occurs and when the T3COF bit is set in the Timer3 interrupt flag register (T3IFR).

Bit 0 – T3OIM Timer3 Overflow Interrupt Mask

If the T3OIM bit is written to ‘1’ and the I bit in SREG is set, the Timer3 overflow interrupt is enabled. The corresponding interrupt is executed if an overflow in Timer3 occurs and when the T3OFF bit is set in the Timer3 interrupt flag register (T3IFR).
