5.0 – 5.1
5.0 Display Control Functions
5.1 Character Configuration
The origin of each character bitmap is in the top left
corner as shown in Figure 38. Adjacent bits in each
byte are horizontally adjacent in the corresponding
character image.
Although the size of the bitmap is fixed by the charac-
ter generator, the actual displayed size of the charac-
ter field can be varied in both dimensions.
5.0 Display Control Functions
If the area outside the character bitmap contains only
zeros, the displayed character size can easily be
increased by increasing FX and FY, as the zeros
ensure that the extra space between displayed char-
acters is blank.
The displayed character width can be set to any value
up to 16 even if each horizontal row of the bitmap is
two bytes wide.
