FX = horizontal character size is 16 pixels (REG[01h] bits 3-0)
FY = vertical character size is 16 pixels (REG[02h] bits 3-0)
Character width
The origin of each character bitmap is the top left corner as shown in Figure 12-1. Adjacent
bits in each byte are horizontally adjacent in the corresponding character image.
Although the size of the bitmap is fixed by the character generator, the actual displayed size
of the character field can be varied in both dimensions.
If the area outside the character bitmap contains only zeros, the displayed character size can
be increased by increasing the horizontal character size (REG[01h] bits 3-0) and the vertical
character size (REG[01h] bits 3-0). The zeros ensure that the extra space between displayed
characters is blank.
