Caution In the first cycle operation of count clock after writing TS0n, an error at a maximum of one
<1> While TE0n is set to 0, TCR0n holds the initial value.
<2> Writing 1 to TS0n sets 1 to TE0n.
<3> As soon as 1 has been written to TS0n and 1 has been set to TE0n, the "TDR0n value" is loaded to
<4> After that, the TCR0n value is counted down according to the count clock.
<1> Writing 1 to TS0n sets TE0n = 1
<2> The write data to TS0n is held until count clock generation.
<3> TCR0n holds the initial value until count clock generation.
<4> On generation of count clock, 0000H is loaded to TCR0n and count starts.

TCR0n to start counting.
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 MD0n0 = 1.
