1. Set the SYNC bits to 1 in TSNC for the channels to be synchronized.
2. When a value is written in 16TCNT in one of the synchronized channels, the same value is
simultaneously written in 16TCNT in the other channels.
3. Set the CCLR1 or CCLR0 bit in 16TCR to have the counter cleared by compare match or input capture.
4. Set the CCLR1 and CCLR0 bits in 16TCR to have the counter cleared synchronously.
5. Set the STR bits in TSTR to 1 to start the synchronized counters.
