Section 12 Timer Z
12.4.4
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 GR to be increased with respect to a single time base.
Figure 12.19 shows an example of the synchronous operation setting procedure.

<Synchronous presetting>
[1] Set the SYNC bits in TMDR to 1.
[2] When a value is written to either of the TCNT counters, the same value is simultaneously written to the
[3] Set bits CCLR1 and CCLR0 in TCR to specify counter clearing by compare match/input capture.
[4] Set bits CCLR1 and CCLR0 in TCR to designate synchronous clearing for the counter clearing source.
[5] Set the STR bit in TSTR to 1 to start the count operation.
