Notes 1: It becomes Hi-Z when reading, and it outputs undefined data when writing.
2: When the external data bus width is 8 bits, the function to output the low-order address from the Di pin while RD or WR is “H” can be selected only
in special area access cycle. Refer to the section on the processor mode for details.
