CDP1852, CDP1852C
Byte-Wide Input/Output Port
Description
The CDP1852 and CDP1852C are parallel, 8-bit, mode-programmable input/output ports.
They are compatible and will interface directly with CDP1800-series microprocessors.
They are also useful as 8-bit address latches when used with the CDP1800 multiplexed address bus and as I/O ports in generalpurpose applications.
The mode control is used to program the device as an input port (mode = 0) or as an output port (mode = 1).
The SR/SR output can be used as a signal to indicate when data is ready to be transferred.
In the input mode, a peripheral device can strobe data into the CDP1852, and microprocessor can read that data by device sel...
