Procedure for Selecting the Synchronizing Mode (Figure 12.15):

1.Set 1 in the SYNC bit of the timer synchro register (TSYR) to use the corresponding channel

in the synchronizing mode.

2.When a value is written in the TCNT in any of the synchronized channels, the same value is

simultaneously written in the TCNT in the other channels.

3.Set the counter to clear with output compare/input capture using bits CCLR2–CCLR0 in the

TCR.

4.Set the counter clear source to synchronized clear using the CCLR2–CCLR0 bits of the TCR.

5.Set the CST bits for the corresponding channels in the TSTR to 1 to start counting in the

TCNT.
