<1> TCRn holds its initial value while operation is stopped (TEn = 0).
<2> Operation is enabled (TEn = 1) by writing 1 to the TSn.
<3> 1 is written to TSn and 1 is set to TEn, and at the same time the value of TDRn is loaded to TCRn to
<4> After that, the TCRn value is counted down according to the count clock.
<1> Operation is enabled (TEn = 1) by writing 1 to the TSn.

<4> On generation of count clock, 0000H is loaded to TCRn and count starts.
start counting.
Start trigger detection signal
clock is generated since count start delays until count clock has been generated. When the
information on count start timing is necessary, an interrupt can be generated at count start
by setting MDn0 = 1.
