AT90S/LS4433
1042H–AVR–04/03
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
hardware when executing the corresponding interrupt handling vector. Alternatively,
TOV1 is cleared by writing a logical “1” to the flag. When the I-bit in SREG and TOIE1
(T im er/Co u n t er1 Ove r flow Inte rrup t En able) an d TO V1 a r e set (o ne) , th e
Timer/Counter1 Overflow Interrupt is executed. In PWM mode, this bit is set when
Timer/Counter1 advances from $0000.
Bit 6 – OCF1: Output Compare Flag 1
The OCF1 bit is set (one) when a Compare Match occurs between the Timer/Counter1
and the data in Output Compare Register 1 (OCR1). OCF1 is cleared by hardware when
executing the corresponding interrupt handling vector. Alternatively, OCF1 is cleared by
writing a logical “1” to the flag. When the I-bit in SREG and OCIE1 (Timer/Counter1
Compare Match Interrupt A Enable) and the OCF1 are set (one), the Timer/Counter1
Compare Match Interrupt is executed.
Bits 5, 4 – Res: Reserved Bits
These bits are reserved bits in the AT90S4433 and always read as 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 hardware when executing the corresponding interrupt handling vector.
Alternatively, ICF1 is cleared by writing a logical “1” 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 AT90S4433 and always reads as zero.
Bit 1 – TOV0: Timer/Counter0 Overflow Flag
The bit TOV0 is set (one) when an overflow occurs in Timer/Counter0. TOV0 is cleared
by hardware when executing the corresponding interrupt handling vector. Alternatively,
TOV0 is cleared by writing a logical “1” to the flag. When the SREG I-bit and TOIE0
(T im er/Co u n t er0 Ove r flow Inte rrup t En able) an d TO V0 a r e set (o ne) , th e
Timer/Counter0 Overflow Interrupt is executed.
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the AT90S4433 and always reads as zero.
