Synchronous operation
Set synchronous
Set to 1 the SYNC bits in TSYR corresponding to the channels to be designated for
synchronous operation.
When the TCNT counter of any of the channels designated for synchronous operation is
written to, the same value is simultaneously written to the other TCNT counters.
Use bits CCLR2 to CCLR0 in TCR to specify TCNT clearing by input capture/output compare,
etc.
Use bits CCLR2 to CCLR0 in TCR to designate synchronous clearing for the counter clearing
source.
Set to 1 the CST bits in TSTR for the relevant channels, to start the count operation.
