Bit 5—Timer Overflow Interrupt Enable (OVIE): Selects whether the OVF interrupt request
(OVI) is enabled or disabled when the OVF flag in TCSR is set to 1.
Note that an OVI interrupt is not requested by TMRX, regardless of the OVIE value.
Bits 4 and 3—Counter Clear 1 and 0 (CCLR1, CCLR0): These bits select the method by which
the timer counter is cleared: by compare-match A or B, or by an external reset input.
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.
The input clock can be selected from either six or three clocks, all divided from the system clock
( ). The falling edge of the selected internal clock triggers the count.
When use of an external clock is selected, three types of count can be selected: at the rising edge,
the falling edge, and both rising and falling edges.
Some functions differ between channel 0 and channel 1, because of the cascading function.
