ETIMSK – Extended
Timer/Counter
Interrupt Mask
Register
2490Q–AVR–06/10
(1)
• Bit 2 – TOIE1: Timer/Counter1, 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/Counter1 Overflow Interrupt is enabled. The corresponding Interrupt Vector
(see “Interrupts” on page 61) is executed when the TOV1 flag, located in TIFR, is set.
Note:
• Bit 7:6 – Reserved Bits
These bits are reserved for future use. For ensuring compatibility with future devices, these bits
must be set to zero when ETIMSK is written.
• Bit 5 – TICIE3: Timer/Counter3, 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/Counter3 Input Capture interrupt is enabled. The corresponding Interrupt
Vector (see “Interrupts” on page 61) is executed when the ICF3 flag, located in ETIFR, is set.
• Bit 4 – OCIE3A: Timer/Counter3, 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/Counter3 Output Compare A Match interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 61) is executed when the OCF3A flag, located in
ETIFR, is set.
• Bit 3 – OCIE3B: Timer/Counter3, 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/Counter3 Output Compare B Match interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 61) is executed when the OCF3B flag, located in
ETIFR, is set.
• Bit 2 – TOIE3: Timer/Counter3, 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/Counter3 Overflow Interrupt is enabled. The corresponding Interrupt Vector
(see “Interrupts” on page 61) is executed when the TOV3 flag, located in ETIFR, is set.
• Bit 1 – OCIE3C: Timer/Counter3, Output Compare C 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/Counter3 Output Compare C Match interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 61) is executed when the OCF3C flag, located in
ETIFR, is set.
• Bit 0 – OCIE1C: Timer/Counter1, Output Compare C 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/Counter1 Output Compare C Match interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 61) is executed when the OCF1C flag, located in
ETIFR, is set.
