Synchronous Operation

In synchronous operation, the values in multiple TCNT counters can be rewritten simultaneously
(synchronous presetting). Also, multiple of TCNT counters can be cleared simultaneously
(synchronous clearing) by making the appropriate setting in TCR.
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 5 can all be designated for synchronous operation.
Example of Synchronous Operation Setting Procedure: Figure 11.10 shows an example of the
synchronous operation setting procedure.
