8. 16-Bit Timer
Bits 6 and 5—Counter Clear 1 and 0 (CCLR1, CCLR0): These bits select how 16TCNT is
cleared.

Notes: 1. 16TCNT is cleared by compare match when the general register functions as an output
Bits 4 and 3—Clock Edge 1 and 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 16TCR2 are ignored.
Phase counting takes precedence.
