11.4.2
In synchronous operation, the values in a number of TCNT counters can be rewritten
simultaneously (synchronous presetting). Also, a number of TCNT counters can be cleared
simultaneously by making the appropriate setting in TCR (synchronous clearing).
Synchronous operation enables TGR to be incremented with respect to a single time base.
Channels 0 to 4 can all be designated for synchronous operation.

Figure 11.12 shows an example of the synchronous operation setting procedure.
Example of Synchronous Operation Setting Procedure
[1] Set to 1 the SYNC bits in TSYR corresponding to the channels to be designated for synchronous
[2] When the TCNT counter of any of the channels designated for synchronous operation is written to,
[3] Use bits CCLR2 to CCLR0 in TCR to specify TCNT clearing by input capture/output compare, etc.
[4] Use bits CCLR2 to CCLR0 in TCR to designate synchronous clearing for the counter clearing source.
[5] Set to 1 the CST bits in TSTR for the relevant channels, to start the count operation.
