Display RAM organization
The display character RAM is organized as 192
×
12 bits.
The general format of each RAM location is as follows.
Bits <11-5> hold character data: 1 out of 128 different
character fonts may be specified (126 customized fonts
plus 2 reserved codes). Bits <4-0> hold attribute data of
the character font, for example, colour, character size etc.

RAM
FORMATS
There are four different formats to be considered:
1.
Customer character code.
2.
Carriage Return code
3.
Space code 1 and Space code 2.
These formats are shown in Tables 70 to 72.
17.5.1.1
Customer character code
If bits <11-5> are in the range 00H to 7CH then this is a
customized character code.
Bits <4-2> select the character colour, a choice of
8 colours are available.
Bit <0> determines whether the character blinks or not.
The actual blinking frequency is determined by the BF bit
in SFR OSCON.
17.5.1.2
Carriage Return code
If bits <11-5> hold 7EH then this is the Carriage Return
code. A transparent pattern will be displayed on the
screen, the current display row will be terminated and the
character stored in the display RAM next to this code will
be displayed at the beginning of the next row.
Bits <4-3> select the size of the characters to be displayed
in the next row. The character size is independently
controlled in both the vertical and the horizontal direction.
Bit <4> controls the vertical size as shown in Table 65 and
bit <3> controls the horizontal size as shown in Table 66.
Figure 34 shows the four different character sizes
available.
Bits <2-1> select the display sub-mode of the next row.
Four sub-modes can be selected (see Table 67) in either
the Frame mode or the TV mode. Therefore a total of
8 different modes are available, these are illustrated in
Figs 35 and 36.
Bit <0> is the end of display control bit and stops the
display function before the last display RAM address
(191 decimal). By combining the ‘end of display’ feature
with the start RAM address (controlled by SFR OSSTART)
the display RAM can be configured into several banks for
fast display data switching. The states of the end of display
control bit are defined in Table 68.

One vertical dot is equal to one horizontal
scan-line width.
One vertical dot is equal to two horizontal
scan-line widths.

One horizontal dot is equal to one OSD clock
width.
One horizontal dot is equal to two OSD clock
widths.

Continue to display in next row.
Stop the display and wait for the next display
field. As soon as the horizontal and vertical
starting position has been reached, continue
to display.
