/CAS
2. As the DRAM interface is not supported in the H8S/2321, LCASE is always 0.
3. CAS is not supported in the H8S/2321.
4. As the DRAM interface is not supported in the H8S/2321, DRAME is always 0.
5. The WDTOVF pin function is not usable on the F-ZTAT version.
6. A low level is output if a WDT overflow occurs while WT/IT is set to 1.
