TIMSK1 – Timer/Counter 1 Interrupt Mask Register
TIFR0 – Timer/Counter 0 Interrupt Flag Register
TIFR1 – Timer/Counter 1 Interrupt Flag Register
• Bits 7:3 – Res: Reserved Bits
These bits are reserved and will always read zero.
• Bit 2 – OCIEnB: Timer/Countern Output Compare Match B Interrupt Enable
When the OCIEnB bit is written to one, and the I-bit in the Status Register is set, the
Timer/Counter Compare Match B interrupt is enabled. The corresponding interrupt is executed if
a Compare Match in Timer/Countern occurs, i.e., when the OCFnB bit is set in the Timer/Coun-
ter Interrupt Flag Register – TIFRn.
• Bit 1 – OCIEnA: Timer/Countern Output Compare Match A Interrupt Enable
When the OCIEnA bit is written to one, and the I-bit in the Status Register is set, the
Timer/Countern Compare Match A interrupt is enabled. The corresponding interrupt is executed
if a Compare Match in Timer/Countern occurs, i.e., when the OCFnA bit is set in the
Timer/Counter n Interrupt Flag Register – TIFRn.
• Bit 0 – TOIEn: Timer/Countern Overflow Interrupt Enable
When the TOIEn bit is written to one, and the I-bit in the Status Register is set, the Timer/Coun-
tern Overflow interrupt is enabled. The corresponding interrupt is executed if an overflow in
Timer/Countern occurs, i.e., when the TOVn bit is set in the Timer/Counter n Interrupt Flag Reg-
ister – TIFRn.
• Bits 7:3 – Res: Reserved Bits
These bits are reserved and will always read zero.
• Bit 2 – OCFnB: Output Compare Flag n B
The OCFnB bit is set when a Compare Match occurs between the Timer/Countern and the data
in OCRnB – Output Compare Registern B. OCFnB is cleared by hardware when executing the
corresponding interrupt handling vector. Alternatively, OCFnB is cleared by writing a logic one to
the flag. When the I-bit in SREG, OCIEnB (Timer/Counter Compare B Match Interrupt Enable),
and OCFnB are set, the Timer/Countern Compare Match Interrupt is executed.
