17.9.6 OCR0B – Timer/Counter0 Output Compare Register B
17.9.7 TIMSK0 – Timer/Counter0 Interrupt Mask Register
242
ATmega128RFA1
The Output Compare Register B contains an 8-bit value that is continuously compared
with the counter value (TCNT0). A match can be used to generate an Output Compare
interrupt, or to generate a waveform output on the OC0B pin.
• Bit 7:0 – OCR0B_7:0 - Output Compare Register
• Bit 7:3 – Res4:0 - Reserved
This bit is reserved for future use. A read access always will return zero. A write access
does not modify the content.
• Bit 2 – OCIE0B - Timer/Counter0 Output Compare Match B Interrupt Enable
When the OCIE0B bit is written to one, and the I-bit in the Status Register is set, the
Timer/Counter0 Compare Match B interrupt is enabled. The corresponding interrupt is
executed if a Compare Match in Timer/Counter0 occurs, i.e., when the OCF0B bit is set
in the Timer/Counter0 Interrupt Flag Register TIFR0.
• Bit 1 – OCIE0A - Timer/Counter0 Output Compare Match A Interrupt Enable
When the OCIE0A bit is written to one, and the I-bit in the Status Register is set, the
Timer/Counter0 Compare Match A interrupt is enabled. The corresponding interrupt is
executed if a Compare Match in Timer/Counter0 occurs, i.e., when the OCF0A bit is set
in the Timer/Counter0 Interrupt Flag Register TIFR0.
• Bit 0 – TOIE0 - Timer/Counter0 Overflow Interrupt Enable
When the TOIE0 bit is written to one, and the I-bit in the Status Register is set, the
Timer/Counter0 Overflow interrupt is enabled. The corresponding interrupt is executed
if an overflow in Timer/Counter0 occurs i.e., when the TOV0 bit is set in the
Timer/Counter0 Interrupt Flag Register TIFR0.
