10.4.3
In synchronizing mode, two or more timer counters can be rewritten simultaneously (synchronized
preset). Multiple timer counters can also be cleared simultaneously using TCR settings
(synchronized clear). Synchronizing mode enables the general registers to be incremented with a
single time base. All five channels can be set for synchronous operation.
Procedure for Selecting Synchronizing Mode (figure 10.26):

1. Set 1 in the SYNC bit of the timer synchro register (TSNC) to use the channels in the
2. When a value is written in TCNT in any of the synchronized channels, the same value is
3. Set the counter to clear with compare match/input capture using bits CCLR1 and CCLR0 in
4. Set the counter clear source to synchronized clear using the CCLR1 and CCLR0 bits.
5. Set the STR bits in TSTR to 1 to start the TCNT count.
