9.3.9
TSYR selects independent operation or synchronous operation for the channel 0 to 2 TCNT
counters. A channel performs synchronous operation when the corresponding bit in TSYR is set to
1.

The write value should always be 0.
Timer Synchro 2 to 0
These bits select whether operation is independent of or
synchronized with other channels.
When synchronous operation is selected, synchronous
presetting of multiple channels, and synchronous clearing
through 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: TCNT_2 to TCNT_0 operates independently
1: TCNT_2 to TCNT_0 performs synchronous operation
(TCNT presetting /clearing is unrelated to other
channels)
TCNT synchronous presetting/synchronous clearing is
possible
