$005) is executed if a CompareB match in Timer/Counter1 occurs, i.e., when the OCF1B bit is
set in the TIFR.
Bit 4 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB325 and always reads zero.
Bit 3 – TICIE1: Timer/Counter1 Input Capture Interrupt Enable
When the TICIE1 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter1 Input Capture Event Interrupt is enabled. The corresponding interrupt (at vector
$003) is executed if a capture-triggering event occurs on pin 31, ICP, i.e., when the ICF1 bit is
set in the TIFR.
Bit 2 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB325 and always reads zero.
Bit 1 – TOIE0: Timer/Counter0 Overflow Interrupt Enable
When the TOIE0 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter0 Overflow interrupt is enabled. The corresponding interrupt (at vector $007) is
executed if an overflow in Timer/Counter0 occurs, i.e., when the TOV0 bit is set in the TIFR.
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB325 and always reads zero.
4.9.4
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 hard-
ware 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 execut-
ing 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 execut-
