GENERAL DESCRIPTION
MTV004 is designed for use in monitor applications to display the built-in characters or symbols onto the
monitor screen. The display operation is enabled by transferring data and control information in the
microcontroller to RAM through a serial data interface. It can execute the full screen display automatically as
well as some specific functions such as character bordering, shadowing, double height, double width and color
control, frame positioning, vertical display height, and windowing effect.
