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.
