(7) Operation of OVF0n flag

(a) Setting OVF0n flag (1)
(b) Clearing OVF0n flag
One-shot pulse output operates correctly in the free-running timer mode or the clear & start mode entered by the
TI00n pin valid edge. The one-shot pulse cannot be output in the clear & start mode entered upon a match between
TM0n and CR00n.
Remark n = 0:
The OVF0n flag is set to 1 in the following case, as well as when TM0n overflows.
Select the clear & start mode entered upon a match between TM0n and CR00n.
Set CR00n to FFFFH.
When TM0n matches CR00n and TM0n is cleared from FFFFH to 0000H
Even if the OVF0n flag is cleared to 0 after TM0n overflows and before the next count clock is counted (before
the value of TM0n becomes 0001H), it is set to 1 again and clearing is invalid.
