Bit 7—Compare Match Interrupt Enable B (CMIEB): Selects whether CMFB interrupt

requests (CMIB) are enabled or disabled when the CMFB flag of TCSR is set to 1.

Bit 7

CMIEB Description

0 CMFB interrupt requests (CMIB) are disabled (Initial value)

1 CMFB interrupt requests (CMIB) are enabled

Bit 6—Compare Match Interrupt Enable A (CMIEA): Selects whether CMFA interrupt

requests (CMIA) are enabled or disabled when the CMFA flag of TCSR is set to 1.

Bit 6

CMIEA Description

0 CMFA interrupt requests (CMIA) are disabled (Initial value)

1 CMFA interrupt requests (CMIA) are enabled

Bit 5—Timer Overflow Interrupt Enable (OVIE): Selects whether OVF interrupt requests

(OVI) are enabled or disabled when the OVF flag of TCSR is set to 1.

Bit 5

OVIE Description

0 OVF interrupt requests (OVI) are disabled (Initial value)

1 OVF interrupt requests (OVI) are enabled

Bits 4 and 3—Counter Clear 1 and 0 (CCLR1 and CCLR0): These bits select the method by

which TCNT is cleared: by compare match A or B, or by an external reset input.

Bit 4 Bit 3

CCLR1 CCLR0 Description

0 0 Clear is disabled (Initial value)

1 Clear by compare match A

1 0 Clear by compare match B

1 Clear by rising edge of external reset input
