(7) Operation of OVF00 flag
(8) One-shot pulse output
216
(a) Setting OVF00 flag (1)
(b) Clearing OVF00 flag
One-shot pulse output operates correctly in the free-running timer mode or the clear & start mode entered by the
TI000 pin valid edge. The one-shot pulse cannot be output in the clear & start mode entered upon a match
between TM00 and CR000.
The OVF00 flag is set to 1 in the following case, as well as when TM00 overflows.
Select the clear & start mode entered upon a match between TM00 and CR000.
Set CR000 to FFFFH.
When TM00 matches CR000 and TM00 is cleared from FFFFH to 0000H
Even if the OVF00 flag is cleared to 0 after TM00 overflows and before the next count clock is counted
(before the value of TM00 becomes 0001H), it is set to 1 again and clearing is invalid.
