1. DESCRIPTION

ꢀOSD function

The M37225M6/M8/MA/MC–XXXSP are single-chip microcomput-

Display characters ............................................... 24 characters ꢀ 2 lines

(It is possible to display 3 lines or more by software)

ers designed with CMOS silicon gate technology. They have a OSD,

Kinds of characters ......... 381 kinds

I C-BUS interface, PWM output, and 12 V withstand, so it is useful

Character display area 16 ꢀ 20 dots

for a channel selection system for TV.

Kinds of character sizes.............................. Block display: 3 kinds

SPRITE display: 1 kinds

The features of the M37225ECSP are similar to those of the

M37225M6-XXXSP except that the chip has a built-in PROM which

can be written electrically. The differences amang M37225M6/M8/

MA/MC–XXXSP are the ROM, RAM size. Accordingly, the following

descriptions will be for the M37225M6-XXXSP.

Kinds of character colors. ................................. 8 colors (R, G, B)

Coloring unit................... character, character background, raster

Display position

Horizontal: 64 levels

Vertical :255 levels

Attribute ........ Border (all-bordered, shadow-bordered), BUTTON

SPRITE display function
