GENERAL DESCRIPTION
MTV021 is designed for monitor applications to display built-in characters or fonts onto monitor screens. The display operation occurs by transferring data and control information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as character background color, bordering, shadowing, blinking, double height and width, font by font color control, frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, windowing effect and shad owing on window.
