Section 12 8-Bit Timers
Bit 7—Compare Match Interrupt Enable B (CMIEB): Selects whether CMFB interrupt
requests (CMIB) are enabled or disabled when the CMFB flag in TCSR is set to 1.
Bit 7
CMIEB
0
1
Bit 6—Compare Match Interrupt Enable A (CMIEA): Selects whether CMFA interrupt
requests (CMIA) are enabled or disabled when the CMFA flag in TCSR is set to 1.

Bit 5—Timer Overflow Interrupt Enable (OVIE): Selects whether OVF interrupt requests
(OVI) are enabled or disabled when the OVF flag in TCSR is set to 1.
Bit 5
OVIE
0
1
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
CCLR1
0
1
Bits 2 to 0—Clock Select 2 to 0 (CKS2 to CKS0): These bits select whether the clock input to
TCNT is an internal or external clock.
Three internal clocks can be selected, all divided from the system clock (φ): φ/8, φ/64, and φ/8192.
The falling edge of the selected internal clock triggers the count.
