MB88310 Datasheet (Fujitsu) - CMOS Input / Output Expander

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.
