[ 30 X 15 DISPLAY RAM ]
Figure 9: Memory Map of Display Registers
The display RAM's address of the row and column number are assigned in order. The display RAM is composed
of 2 register groups (Character & Attribute Register, Frame Control Register).
The display area in the monitor screen is 30 columns X 15 rows, so the related "Character & Attribute Registers"
are also 30 columns X 15 rows. Each register has a character address and characteristics corresponding to the
display location on the screen, and one register is composed of 16-buts. The lower 8-bits and the extended 1-bit
(the MSB of row/ column address) are used for selecting a font out of 464 ROM fonts, and upper 8-bits are
assigned to give a character attribute to a selected font.
"Frame Control Registers" are in the 15th row. "Frame Control Register 0
2" control with frame unit display
position of the OSD, height of character, blinking, scrolling, and etc function. "Frame Control Register 3" select
extended codes to control 'Blink', 'Shadow', 'Character intensity', and 'Raster intensity'. "Frame Control Register
4" specify the reference value for "Auto height control" and "Row to row space". "Frame Control Register 5
13"
control in relation to 4-windows.
Each register's configurations shown in "Figure 10 : Register Description (13p) ". For more detailed
information, refer to "Table 7 : Register Description (14p) ".
