Preliminary
MEMORY MAP
The display RAM's address of the row and column number are assigned in order. The display RAM is composed of
4 register groups (character & attribute register, row attribute register, frame control register, and V-AMP control
register).
The display area in the monitor screen is 30 column
×
15 row, so the related character & attribute registers are also
30 column
×
15 row. Each register has a character address and characteristics corresponding to the display
location on the screen, and one register is composed of 16 bits. The lower 9 bits select the font from the 448 ROM
fonts, and the upper 7 bits give font characteristics to the selected font.
The row attribute register takes up the display RAM's 31st column. It provides raster color, raster color intensity,
character color intensity, horizontal & vertical character size, box, border, and shadow features in units of row.
The frame control registers are in the 16th row. It controls OSD's display location, character height, scroll, and
fade-in/out in units of frame.
The V-AMP control registers are also located in the 16th row.
