Timer/Counter Interrupt Flag Register – TIFR
Bit 7 – TOV1: Timer/Counter1 Overflow Flag
The TOV1 is set (one) when an overflow occurs in Timer/Counter1. TOV1 is cleared by the
hardware when executing the corresponding interrupt handling vector. Alternatively, TOV1 is
cleared by writing a logic one to the flag. When the I-bit in SREG, and TOIE1 (Timer/Counter1
Overflow Interrupt Enable), and TOV1 are set (one), the Timer/Counter1 Overflow Interrupt is
executed. In PWM mode, this bit is set when Timer/Counter1 changes counting direction at
$0000.
Bit 6 – OCF1A: Output Compare Flag 1A
The OCF1A bit is set (one) when compare match occurs between the Timer/Counter1 and the
data in OCR1A - Output Compare Register 1A. OCF1A is cleared by the hardware when exe-
cuting the corresponding interrupt handling vector. Alternatively, OCF1A is cleared by writing a
logic one to the flag. When the I-bit in SREG, and OCIE1A (Timer/Counter1 Compare match
InterruptA Enable), and the OCF1A are set (one), the Timer/Counter1 Compare A match Inter-
rupt is executed.
Bit 5 – OCF1B: Output Compare Flag 1B
The OCF1B bit is set (one) when compare match occurs between the Timer/Counter1 and the
data in OCR1B - Output Compare Register 1B. OCF1B is cleared by the hardware when exe-
cuting the corresponding interrupt handling vector. Alternatively, OCF1B is cleared by writing a
logic one to the flag. When the I-bit in SREG, and OCIE1B (Timer/Counter1 Compare match
InterruptB Enable), and the OCF1B are set (one), the Timer/Counter1 Compare B match Inter-
rupt is executed.
Bit 4 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB355 and always reads zero.
Bit 3 – ICF1: - Input Capture Flag 1
The ICF1 bit is set (one) to flag an input capture event, indicating that the Timer/Counter1
value has been transferred to the input capture register - ICR1. ICF1 is cleared by the hard-
ware when executing the corresponding interrupt handling vector. Alternatively, ICF1 is
cleared by writing a logic one to the flag. When the SREG I-bit, and TICIE1 (Timer/Counter1
Input Capture Interrupt Enable), and ICF1 are set (one), the Timer/Counter1 Capture Interrupt
is executed.
Bit 2 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB355 and always reads zero.
Bit 1 – TOV: Timer/Counter0 Overflow Flag
The bit TOV0 is set (one) when an overflow occurs in Timer/Counter0. TOV0 is cleared by the
hardware when executing the corresponding interrupt handling vector. Alternatively, TOV0 is
cleared by writing a logic one to the flag. When the SREG I- bit, and TOIE0 (Timer/Counter0
Overflow Interrupt Enable), and TOV0 are set (one), the Timer/Counter0 Overflow interrupt is
executed.
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB355 and always reads zero.
