Counter Start
0 TCNTn count operation is stopped
1 TCNTn performs count operation
(n = 5 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 Synchronization
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 = 5 to 0)
Notes: 1.
2.
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.
