Section 11 16-Bit Timer Pulse Unit (TPU)
11.3.11 Timer Synchronous Register B (TSYRB)
TSYRB selects independent operation or synchronous operation for the TCNT counters of
channels 6 to 11. A channel performs synchronous operation when the corresponding bit in
TSYRB is set to 1.

Timer Synchronization 11 to 6
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_11 to TCNT_6 operates independently
1: TCNT_11 to TCNT_6 performs synchronous
(TCNT presetting /clearing is unrelated to
other channels)
operation (TCNT synchronous presetting/
synchronous clearing is possible)
