Note:
If 0 is written to the CST bit during operation with the TIOC pin designated for output,
the counter stops but the TIOC pin output compare output level is retained. If TIOR
is written to when the CST bit is cleared to 0, the pin output level will be changed to
the set initial output value.

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.
