(Revision 1.1)
GENERAL DESCRIPTION
MTV038 is designed for CRT/LCD monitor applications
to display built-in characters or fonts onto monitor screens.
The display operation occurs by transferring data and con-
trol 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 charac-
ter background, bordering, shadowing, blinking, double
height and width, font by font color control, character but-
ton boxes, frame positioning, frame size control by charac-
ter height and row-to-row spacing, horizontal display
resolution, full-screen erasing, fade-in/fade-out effect, win-
dowing effect, shadowing on window and full-screen self-
test pattern generator.
MTV038 provides 544 fonts including 512 standard
fonts and 32 multi-color fonts and 2 font sizes, 12x16 or
12x18 for more efficacious applications. 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
with 12-bit resolution at the speed related to the OSD pixel
clock. And the R, G, BIN input level can be programming
by software. 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.
