Bit 7
CMIEB
Bit 6 – Compare-match Interrupt Enable A (CMIEA): This bit selects whether to request
compare-match interrupt A (CMIA) when compare-match flag A (CMFA) in the timer
control/status register (TCSR) is set to “1.”
Bit 6
CMIEA Description
Bit 5 – Timer Overflow Interrupt Enable (OVIE): This bit selects whether to request a timer
overflow interrupt (OVI) when the overflow flag (OVF) in the timer control/status register (TCSR)
is set to “1.”
Bit 5
OVIE
Bits 4 and 3 – Counter Clear 1 and 0 (CCLR1 and CCLR0): These bits select how the timer
counter is cleared: by compare-match A or B or by an external reset input.

Bits 2, 1, and 0 – Clock Select (CKS2, CKS1, and CKS0): These bits select the internal or
external clock source for the timer counter. For the external clock source they select whether to
increment the count on the rising or falling edge of the clock input, or on both edges. For the
internal clock sources the count is incremented on the falling edge of the clock input.
