Section 10 16-Bit Integrated Timer Unit (ITU)
Bits 6 and 5—Counter Clear 1/0 (CCLR1, CCLR0): These bits select how TCNT is cleared.
Notes: 1. TCNT is cleared by compare match when the general register functions as an output
Bits 4 and 3—Clock Edge 1/0 (CKEG1, CKEG0): These bits select external clock input edges
when an external clock source is used.
When channel 2 is set to phase counting mode, bits CKEG1 and CKEG0 in TCR2 are ignored.
Phase counting takes precedence.
Bits 2 to 0—Timer Prescaler 2 to 0 (TPSC2 to TPSC0): These bits select the counter clock
source.
