This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. When the serial interface is selected,then D7 serves as the serial data input terminal and D6 serves as the serial clock input terminal.At this time,D0-D5 are set to high impedence. When the chip select is inactive,D0 to D7 are set to high impedance. Page 04 of 15 AZ DISPLAYS, INC.
