(12) One-shot pulse output with external trigger
(13) Operation of OVF00 flag
<1> Do not input the external trigger again while the one-shot pulse is being output. To output the one-shot
<2> Do not set the 16-bit timer capture/compare registers 000 and 010 (CR000 and CR010) to 0000H.
<1> The OVF00 flag is also set to 1 in the following case.
<2> Even if the OVF00 flag is cleared before the next count clock is counted (before TM00 becomes 0001H)
pulse again, wait until the current one-shot pulse output is completed.
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.
When TM00 is counted up from FFFFH to 0000H.
after the occurrence of a TM00 overflow, the OVF00 flag is re-set newly and clear is disabled.
CR000 is set to FFFFH.
