Timer/Counter Interrupt Mask
Register – TIMSK

ATmega8535(L)
(1)
Note:
• Bit 5 – TICIE1: Timer/Counter1, Input Capture Interrupt Enable
When this bit is written to one and the I-flag in the Status Register is set (interrupts glo-
bally enabled), the Timer/Counter1 Input Capture interrupt is enabled. The
corresponding Interrupt Vector (see “Interrupts” on page 45) is executed when the ICF1
Flag, located in TIFR, is set.
• Bit 4 – OCIE1A: Timer/Counter1, Output Compare A Match Interrupt Enable
When this bit is written to one and the I-flag in the Status Register is set (interrupts glo-
bally enabled), the Timer/Counter1 output compare A match interrupt is enabled. The
corresponding Interrupt Vector (see “Interrupts” on page 45) is executed when the
OCF1A Flag, located in TIFR, is set.
• Bit 3 – OCIE1B: Timer/Counter1, Output Compare B Match Interrupt Enable
When this bit is written to one and the I-flag in the Status Register is set (interrupts glo-
bally enabled), the Timer/Counter1 output compare B match interrupt is enabled. The
corresponding Interrupt Vector (see “Interrupts” on page 45) is executed when the
OCF1B Flag, located in TIFR, is set.
• 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 glo-
bally enabled), the Timer/Counter1 overflow interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 45) is executed when the TOV1 Flag, located
in TIFR, is set.
