Timer Synchronous operation 2 to 0

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_2 to TCNT_0 operates independently (TCNT

presetting /clearing is unrelated to other channels)

1: TCNT_2 to TCNT_0 performs synchronous operation

TCNT synchronous presetting/synchronous clearing

is possible
