Description
Timer Synchronous operation 4 and 3
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_4 and TCNT_3 operate independently
1: TCNT_4 and TCNT_3 performs synchronous
TCNT synchronous presetting/synchronous clearing
is possible
Reserved
These bits are always read as 0. The write value
should always be 0.
Timer Synchronous operation 2 to 0
These bits are used to select whether operation is
independent of or synchronized with other channels.

synchronous presetting of multiple channels, and
synchronous clearing by counter clearing on another

To set synchronous operation, the SYNC bits for at

0: TCNT_2 to TCNT_0 operates independently
