CMOS Programmable I, O Interface
Description
THE CDP1851 and CDP1851C are CMOS programmable twoport I, Os designed for use as general-purpose I, O devices. They are directly compatible with CDP1800-series microprocessors functioning at maximum clock frequency. Each port can be programmed in either byte-I, O or bit-programmable modes for interfacing with peripheral devices such as printers and keyboards. Both ports A and B can be separately programmed to be 8-bit inp
