Section 10 16-Bit Timer Pulse Unit (TPU)
10.3.9
TSYR selects independent operation or synchronous operation for the TCNT counters of channels
0 to 5. A channel performs synchronous operation when the corresponding bit in TSYR is set to 1.

These bits are always read as 0. The write value should
always be 0.
Timer Synchronization 5 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_5 to TCNT_0 operate independently (TCNT
1: TCNT_5 to TCNT_0 perform synchronous operation
Description
presetting/clearing is unrelated to other channels)
(TCNT synchronous presetting/synchronous clearing
is possible)
