This pin functions as the WDTOVF pin function in ZTAT, and masked ROM products, and in the H8S/2352.
In the H8S/2357F-ZTAT, the WDTOVF pin function is not available, because this pin is used as the FWE
pin.
In the H8S/2398, H8S/2394, H8S/2392, and H8S/2390, the WDTOVF pin function is not available,
because this pin is used as the V
In ROMless version, ROM is not supported.
