Timer/Counter1 Interrupt Flag Register – TIFR1
• Bit 7, 6 – Res: Reserved Bits
• Bit 5 – ICF1: Timer/Counter1, Input Capture Flag
• Bit 4, 3 – Res: Reserved Bits
• Bit 2 – OCF1B: Timer/Counter1, Output Compare B Match Flag
• Bit 1 – OCF1A: Timer/Counter1, Output Compare A Match Flag
• Bit 0 – TOV1: Timer/Counter1, Overflow Flag
Initial Value
Read/Write
These bits are unused bits in the Atmel
zero.
This flag is set when a capture event occurs on the ICP1 pin. When the Input Capture
Register (ICR1) is set by the WGM13:0 to be used as the TOP value, the ICF1 Flag is set
when the counter reaches the TOP value.
ICF1 is automatically cleared when the Input Capture Interrupt Vector is executed. Alter-
natively, ICF1 can be cleared by writing a logic one to its bit location.
These bits are unused bits in the Atmel ATA6612/ATA6613, and will always read as zero.
This flag is set in the timer clock cycle after the counter (TCNT1) value matches the Out-
put Compare Register B (OCR1B).
Note that a Forced Output Compare (FOC1B) strobe will not set the OCF1B Flag.
OCF1B is automatically cleared when the Output Compare Match B Interrupt Vector is
executed. Alternatively, OCF1B can be cleared by writing a logic one to its bit location.
This flag is set in the timer clock cycle after the counter (TCNT1) value matches the Out-
put Compare Register A (OCR1A).
Note that a Forced Output Compare (FOC1A) strobe will not set the OCF1A Flag.
OCF1A is automatically cleared when the Output Compare Match A Interrupt Vector is
executed. Alternatively, OCF1A can be cleared by writing a logic one to its bit location.
The setting of this flag is dependent of the WGM13:0 bits setting. In Normal and CTC
modes, the TOV1 Flag is set when the timer overflows. Refer to
for the TOV1 Flag behavior when using another WGM13:0 bit setting.
TOV1 is automatically cleared when the Timer/Counter1 Overflow Interrupt Vector is exe-
cuted. Alternatively, TOV1 can be cleared by writing a logic one to its bit location.
