Description
Timer Synchro 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.

Reserved
These bits are always read as 0. The write value should
always be 0.
