TECHNOLOGY
The vertical display center for full screen display could be figured out according to the information of vertical
starting position register (VERTD) and VFLB input. The vertical delay starting from the leading edge of VFLB,
is calculated with the following equation:
Vertical delay time = ( VERTD * 4 + 1 ) * H Where H = one horizontal line display time
Note:" v " means the nth line in the character would be repeated once, while " - " means the nth line in the
character would not be repeated.
3.4 Horizontal display control
The horizontal display control is used to generate control timing for horizontal display based on double char-
acter width bit (CWS), horizontal positioning register (HORD), horizontal resolution register (HORR), and
HFLB input. A horizontal display line consists of (HORR*12) dots which include 360 dots for 30 display char-
acters and the remaining dots for blank region. The horizontal delay starting from HFLB leading edge is calcu-
lated with the following equation,
Horizontal delay time = ( HORD * 6 + 49) * P Where P = 1 XIN pixel display time
3.5 Display & Row control registers
The internal RAM contains display and row control registers. The display registers have 450 locations which
are allocated between (row 0, column 0) to (row 14, column 29), as shown in Figure 4. Each display register
has its corresponding character address on ADDRESS byte, its corresponding background color, 1 blink bit
and its corresponding color bits on ATTRIBUTE bytes. The row control register is allocated at column 30 for
row 0 to row 14, it is used to set character size to each respective row. If double width character is chosen,
only even column characters could be displayed on screen and the odd column characters will be hidden.
