3.6 User Font RAM
The user font RAM has 288 locations which are allocated between row 0/column 0 and row 7/column
35 to specify 8 user-programmable fonts, as shown in Figure 5. Each programmable font consists of a
12x18 dot matrix. Each row of dot matrix consists of 2 bytes of data which include 4 dummy bits as
shown in figure 6. That is, the dot matrix data of each font is stored in 36-byte registers. For example,
font 0 is stored in row 0 from column 0 to column 35 and font 1 is stored in row 1 from column 0 to col-
umn 35, etc.

3.7 Character ROM
The character ROM contains 248 built-in characters and symbols from addresses 0 to 247. Each char-
acter and symbol consists of a 12x18 dot matrix. The detail pattern structures for each character and
symbol are shown in 10.0“CHARACTER AND SYMBOL PATTERN” on page 15.
3.8 Luminance & Border Generator
There are 2 shift registers included in the design which can shift out of luminance and border dots to the
color encoder. The bordering and shadowing feature is configured in this block. For bordering effect,
the character will be enveloped with blackedge on 4 sides. For shadowing effect, the character is envel-
oped 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 to 11 on row 15 of the memory map, as shown in
Figure 4. Window 1 has the highest priority and window 4 has the least, when 2 windows are overlap-
ping. More detailed information is described as follows:
