1 Introduction
This application note describes the hardware required to implement an interface between
the SED1354 Color Graphics LCD/CRT Controller and the Motorola MC68328
‘Dragonball’ Microprocessor. By implementing a dedicated display refresh memory, the
SED1354 can reduce system power consumption, improve image quality, and increase
system performance as compared to the Dragonball’s on-chip LCD controller.
The designs described in this document are presented only as examples of how such
interfaces might be implemented. This application note will be updated as appropriate.
