In 16-bit mode the OCR0B register contains the high byte of the 16-bit Output Compare Regis-

ter. To ensure that both the high and the low bytes are written simultaneously when the CPU

writes to these registers, the access is performed using an 8-bit temporary high byte register

(TEMP). This temporary register is shared by all the other 16-bit registers. See “Accessing Reg-

isters in 16-bit Mode” on page 81.

TIMSK – Timer/Counter0 Interrupt Mask Register

• Bit 4 – 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/Counter 0 Interrupt Flag Register – TIFR0.

• Bit 3 – OCIE0B: Timer/Counter 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/Counter Compare Match B interrupt is enabled. The corresponding interrupt is executed if

a Compare Match in Timer/Counter occurs, i.e., when the OCF0B bit is set in the Timer/Counter

Interrupt Flag Register – TIFR0.

• Bit 1 – 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/Counter 0 Inter-

rupt Flag Register – TIFR0.

• Bit 0 – TICIE0: Timer/Counter0, Input Capture Interrupt Enable

When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally

enabled), the Timer/Counter1 Input Capture interrupt is enabled. The corresponding Interrupt

Vector (See “Interrupts” on page 50.) is executed when the ICF0 flag, located in TIFR, is set.
