NOTE:
that the processor waveforms meet the parameters in the Waveforms Section of this data sheet to ensure proper operation. The Processor wave-
forms are not required to be synchronous to CLK. They are shown that way to clarify the illustration.
These processor signals are meant to be representative. The actual shape of the waveforms will be set by the microprocessor used. Verify

Select the MSByte of the output holding register for output.
Assert RD low to output data on C0-7. (Must wait for 6 CLKs after loading the holding registers).
Select other bytes of holding register by changing A0-2 and asserting RD.
