Question a printer has an 8-bit parallel centronics, Ask an Expert

Engineering

Question: A printer has an 8-bit parallel Centronics interface that consists of an 8-bit parallel data bus and three control lines. DSTB* is an active-low pulsed data strobe that indicates to the printer that the data on the data bus is valid. BUSY* is an output from the printer that, when high, indicates to the computer that the printer cannot accept data, ACKNGL* is a active-low response from the printer to DSTB* and indicates that the printer has captured the data. Design a suitable interface between a computer and the printer using a 68230 PVT, and write a program to control the PUT.
