16.11.13 TIFR – Timer/Counter1 Interrupt Flag Register
126
ATtiny261/ATtiny461/ATtiny861
• Bit 2 - TOIE1: Timer/Counter1 Overflow Interrupt Enable
When the TOIE1 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter1 Overflow interrupt is enabled. The corresponding interrupt (at vector $004) is
executed if an overflow in Timer/Counter1 occurs. The Overflow Flag (Timer1) is set (one) in the
Timer/Counter Interrupt Flag Register - TIFR.
• Bit 7- OCF1D: Output Compare Flag 1D
The OCF1D bit is set (one) when compare match occurs between Timer/Counter1 and the data
value in OCR1D - Output Compare Register 1D. OCF1D is cleared by hardware when executing
the corresponding interrupt handling vector. Alternatively, OCF1D is cleared, after synchroniza-
tion clock cycle, by writing a logic one to the flag. When the I-bit in SREG, OCIE1D, and OCF1D
are set (one), the Timer/Counter1 D compare match interrupt is executed.
• Bit 6 - OCF1A: Output Compare Flag 1A
The OCF1A bit is set (one) when compare match occurs between Timer/Counter1 and the data
value in OCR1A - Output Compare Register 1A. OCF1A is cleared by hardware when executing
the corresponding interrupt handling vector. Alternatively, OCF1A is cleared, after synchroniza-
tion clock cycle, by writing a logic one to the flag. When the I-bit in SREG, OCIE1A, and OCF1A
are set (one), the Timer/Counter1 A compare match interrupt is executed.
• Bit 5 - OCF1B: Output Compare Flag 1B
The OCF1B bit is set (one) when compare match occurs between Timer/Counter1 and the data
value in OCR1B - Output Compare Register 1A. OCF1B is cleared by hardware when executing
the corresponding interrupt handling vector. Alternatively, OCF1B is cleared, after synchroniza-
tion clock cycle, by writing a logic one to the flag. When the I-bit in SREG, OCIE1B, and OCF1B
are set (one), the Timer/Counter1 B compare match interrupt is executed.
• Bit 2 - TOV1: Timer/Counter1 Overflow Flag
In Normal Mode and Fast PWM Mode the TOV1 bit is set (one) each time the counter reaches
TOP at the same clock cycle when the counter is reset to BOTTOM. In Phase and Frequency
Correct PWM Mode the TOV1 bit is set (one) each time the counter reaches BOTTOM at the
same clock cycle when zero is clocked to the counter.
The bit TOV1 is cleared by hardware when executing the corresponding interrupt handling vec-
tor. Alternatively, TOV1 is cleared, after synchronization clock cycle, by writing a logical one to
the flag. When the SREG I-bit, and TOIE1 (Timer/Counter1 Overflow Interrupt Enable), and
TOV1 are set (one), the Timer/Counter1 Overflow interrupt is executed.
