Section 10 16-Bit Integrated Timer Unit (ITU)
10.4.3
The synchronization function enables two or more timer counters to be synchronized by writing
the same data to them simultaneously (synchronous preset). With appropriate TCR settings, two or
more timer counters can also be cleared simultaneously (synchronous clear). Synchronization
enables additional general registers to be associated with a single time base. Synchronization can
be selected for all channels (0 to 4).
Sample Setup Procedure for Synchronization: Figure 10.26 shows a sample procedure for
setting up synchronization.

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