13.11.19 Timer/Counter1 Interrupt Flag Register – TIFR1
13.11.20 Timer/Counter3 Interrupt Flag Register – TIFR3
7679H–CAN–08/08
• Bit 2 – OCIEnB: 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/Countern Output Compare B Match interrupt is enabled. The corresponding
Interrupt Vector
TIFRn, is set.
• Bit 1 – OCIEnA: 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/Countern Output Compare A Match interrupt is enabled. The corresponding
Interrupt Vector
TIFRn, is set.
• Bit 0 – TOIEn: Timer/Counter 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/Countern Overflow interrupt is enabled. The corresponding Interrupt Vector
(See “Interrupts” on page
• Bit 7..6 – Reserved Bits
These bits are reserved for future use.
• Bit 5 – ICFn: Input Capture Flag
This flag is set when a capture event occurs on the ICPn pin. When the Input Capture Register
(ICRn) is set by the WGMn3:0 to be used as the TOP value, the ICFn flag is set when the
counter reaches the TOP value.
ICFn is automatically cleared when the Input Capture Interrupt Vector is executed. Alternatively,
ICFn can be cleared by writing a logic one to its bit location.
• Bit 4 – Reserved Bit
This bit is reserved for future use.
• Bit 3 – OCFnC: Output Compare C Match Flag
This flag is set in the timer clock cycle after the counter (TCNTn) value matches the Output
Compare Register C (OCRnC).
Note that a Forced Output Compare (FOCnC) strobe will not set the OCFnC flag.
OCFnC is automatically cleared when the Output Compare Match C Interrupt Vector is exe-
cuted. Alternatively, OCFnC can be cleared by writing a logic one to its bit location.
