Counter Start 2 to 0
0 TCNTn count operation is stopped
1 TCNTn performs count operation
(n = 2 to 0)
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.

Timer Synchro
0 TCNTn operates independently (TCNT presetting/clearing
is unrelated to other channels)
1 TCNTn performs synchronous operation
TCNT synchronous presetting/synchronous clearing is possible
(n = 2 to 0)
Notes: 1. To set synchronous operation, the SYNC bits for at least two channels must be set to 1.
2. 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.
