GENERAL DESCRIPTION
MTV030 is designed for monitor applications to display
built-in characters or fonts onto monitor screens. The dis-
play operation occurs by transferring data and control infor-
mation from the micro-controller to RAM through a serial
data interface. It can execute full-screen display automati-
cally, as well as specific functions such as character back-
ground, 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, shadowing on window
and full-screen self-test pattern generator.
MTV030 provides true 512 fonts including 496 standard
fonts and 16 multi-color fonts and 2 font sizes, 12x16 or
12x18 for more efficacious applications. So each one of the
512 fonts can be displayed at the same time. The full OSD
menu is formed by 15 rows x 30 columns, which can be
positioned anywhere on the monitor screen by changing
vertical or horizontal delay.
The auto sizing video measurement module measure
the timing relationship among HFLB, VFLB, and R, G, BIN
at the speed related to the OSD resolution. MCU can get
the measurement data, active video, front porth and back
porth, through I
2
C bus read/write operation to keep the
appropriate display size and center.
