3.7 Character ROM
The character ROM contains 128 built-in characters and symbols. Each character and symbol consists of
12x16 matrix dots. The detailed pattern structures for each character and symbols are shown in
Section 10.0
.
All alphanumeric characters are specially designed by leaving a blank dot space on 4 sides, and this blank
space is occupied by the blackedge dots if the bordering or shadowing effect is activated.
3.8 12-Bit Shift Register
There are 2 shift registers included in the design which can shift out luminance and border dots to the color
encoder. The bordering and shadowing feature is configured in this block. For a bordering effect, the character
will be enveloped with blackedge on 4 sides. For shadowing effect, the character is enveloped with blackedge
on right and bottom sides only.
3.9 Window and Frame Control
The display frame position is completely controlled by the contents of VERTD and HORD. The window size
and position control are specified in columns 0-8 on row 10 of the memory map, as shown in Figure 4. Window
1 has the highest priority and window 3 has the lowest when 2 windows are overlapping. More detailed
information is described below:
