MB88310 CMOS Input / Output Expander

The MB 88310/88311 have two interfaces: One is the processor interface; CS, LDI, and DI3-DIO, which are used for the processor to communicate with the MB 88310/88311 devices. Another is the expansion I/O ports; Ports A, B, C, and D, which serve as an expansion of the processor's I/O. Table 1 - PIN.
