Section 10 16-Bit Timer Pulse Unit (TPU)
10.3.9
TSYR is an 8-bit readable/writable register that selects independent operation or synchronous
operation for the channel 0 to 5 TCNT counters. A channel performs synchronous operation when
the corresponding bit in TSYR is set to 1.

These bits are used to select whether operation is
independent of or synchronized with other channels.
When synchronous operation is selected, the TCNT
synchronous presetting of multiple channels, and
synchronous clearing by 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 CCLR0 to CCLR2 in TCR.
0: TCNT_0 to TCNT_5 operates independently
1: TCNT_0 to TCNT_5 performs synchronous
