10. Multifunction Timer Pulse Unit (MTU)
Procedure for Selecting the Synchronizing Mode (Figure 10.14):
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 to CCLR0 in the
TCR.
4. Set the counter clear source to synchronized clear using the CCLR2 to 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.
