(12) One-shot pulse output with external trigger
<1>
Do not input the external trigger again while the one-shot pulse is output. To output the one-shot pulse
again, wait until the current one-shot pulse output is completed.
<2>
Do not set the 16-bit timer capture/compare registers 000 and 010 (CR000 and CR010) to 0000H.
(13) Operation of OVF00 flag
<1>
The OVF00 flag is also set to 1 in the following case.
Either of the clear & start mode entered on a match between TM00 and CR000, clear & start at the valid
edge of the TI000 pin, or free-running mode is selected.
CR000 is set to FFFFH.
When TM00 is counted up from FFFFH to 0000H.

Even if the OVF00 flag is cleared before the next count clock is counted (before TM00 becomes 0001H)
after the occurrence of a TM00 overflow, the OVF00 flag is re-set newly and clear is disabled.
