Note: * These counters can be used as up/down-counters only in phase counting mode or
when counting overflow/underflow on another channel. In other cases they function
as up-counters.

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.
