Note 1: The CMP and IC events are connected to

the same interrupt vector.

The OVF event is mapped on a separate vector

(see Interrupts chapter).

They generate an interrupt if the enable bit is set in

the ATCSR register and the interrupt mask in the

CC register is reset (RIM instruction).

Note 2: Only if CK0=1 and CK1=0 (fCOUNTER =

fLTIMER)
