TSYR selects independent operation or synchronous operation for TCNT in channels 0 to 2.
Synchronous operation is performed in the channel when the corresponding bit in TSYR is set to
1.

The write value should always be 0.
Timer Synchro 2 to 0
Select whether operation is independent of or
synchronized with other channels.
When synchronous operation is selected, synchronous
presetting of multiple channels and synchronous clearing
due to counter clearing on another channel are possible.
To set synchronous operation, the SYNC bits for at least
two channels must be set to 1. To set synchronous
clearing, in addition to the SYNC bit, the TCNT clearing
source must also be set by means of bits CCLR2 to
CCLR0 in TCR.
0: TCNTn operates independently
1: TCNTn performs synchronous operation
(TCNT presetting/clearing is unrelated to other
channels)
TCNT synchronous presetting/synchronous clearing is
possible
