Caution In the first cycle operation of count clock after writing TSmn, an error at a maximum of one
<1> While TEmn is set to 0, TCRmn holds the initial value.
<2> Writing 1 to TSmn sets 1 to TEmn.
<3> As soon as 1 has been written to TSmn and 1 has been set to TEmn, the “TDRmn value” is loaded to
<4> After that, the TCRmn value is counted down according to the count clock.
<1> Writing 1 to TSmn sets TEmn = 1
<2> The write data to TSmn is held until count clock generation.
<3> TCRmn holds the initial value until count clock generation.
<4> On generation of count clock, 0000H is loaded to TCRmn and count starts.

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 MDmn0 = 1.
