Enhanced Super On-Screen Display 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, bor- dering, shadowing, blinking, double height and width, font by font color control, frame positioning, frame size control by character height and row-to-row spac- ing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, windowing effect and shad- owing on window. MTV021 provides 256 standard and 16 multi-color characters and graphic fonts for more efficacious applications. The full OSD menu is formed by 15 rows x 30 columns, which can be positioned any- where on the monitor screen by changing vertical or horizontal delay. Moreover, MTV021 also provides 8 PWM DAC channels with 8-bit resolution and a PWM clock out- put for external digital-to-analog control.
