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) and HFLB input. A horizontal display line
includes 360 dots for 30 display characters and the remaining dots for blank region. The horizontal delay
starting from HFLB leading edge is calculated 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 and Figure 5. Each dis-
play 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 col-
umn 30 for row 0 to row 14 of attribute bytes, 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.
