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.
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.
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 (ø): ø/8, ø/64, and ø/8192. 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.
Note: * If the count input of channel 0 is the TCNT1 overflow signal and that of channel 1 is the TCNT0 compare match
