Timer/Counter
Interrupt Flag Register
– ETIFR
2513K–AVR–07/09
(1)
Note:
• Bit 5 – ICF3: Timer/Counter3, Input Capture Flag
This flag is set when a capture event occurs on the ICP3 pin. When the Input Capture Register
(ICR3) is set by the WGMn3:0 to be used as the TOP value, the ICF3 Flag is set when the coun-
ter reaches the TOP value.
ICF3 is automatically cleared when the Input Capture Interrupt Vector is executed. Alternatively,
ICF3 can be cleared by writing a logic one to its bit location.
• Bit 4 – OCF3A: Timer/Counter3, Output Compare A Match Flag
This flag is set in the timer clock cycle after the counter (TCNT3) value matches the Output
Compare Register A (OCR3A).
Note that a Forced Output Compare (FOC3A) strobe will not set the OCF3A Flag.
OCF3A is automatically cleared when the Output Compare Match A Interrupt Vector is exe-
cuted. Alternatively, OCF3A can be cleared by writing a logic one to its bit location.
• Bit 3 – OCF3B: Timer/Counter3, Output Compare B Match Flag
This flag is set in the timer clock cycle after the counter (TCNT3) value matches the Output
Compare Register B (OCR3B).
Note that a Forced Output Compare (FOC3B) strobe will not set the OCF3B Flag.
OCF3B is automatically cleared when the Output Compare Match B Interrupt Vector is exe-
cuted. Alternatively, OCF3B can be cleared by writing a logic one to its bit location.
• Bit 2 – TOV3: Timer/Counter3, Overflow Flag
The setting of this flag is dependent of the WGMn3:0 bits setting. In normal and CTC modes, the
TOV3 Flag is set when the timer overflows. Refer to
behavior when using another WGMn3:0 bit setting.
TOV3 is automatically cleared when the Timer/Counter3 Overflow Interrupt Vector is executed.
Alternatively, TOV3 can be cleared by writing a logic one to its bit location.
