GENERAL DESCRIPTION
MTV016 is designed for use in monitor applications to display the built-in characters or symbols onto a
monitor screen. The display operation occurs by transferring data and control information in the micro-
controller to RAM through a serial data interface. It can execute a full screen display automatically and
specific functions such as character bordering, shadowing, double height and width, font by font color
control, frame positioning, frame size control by character height and horizontal display resolution, and
windowing effect.
