The function is the same as ITU0.
Overflow flag
0 [Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF.
1 [Setting condition]
The TCNT value overflows (from H'FFFF to H'0000)
or underflows (from H'0000 to H'FFFF)
Notes: Bit functions are the same as for ITU0.
* Only 0 can be written, to clear the flag.
