Notes: 1. If the current mode supports multiple pages, a page
number in BH must be given.
2. If the pixel color (AL) is specified with bit 7 set,
the color bits of the pixel are XORed with the color
bits of the current pixel at the specified
coordinate. You can use this feature to write
characters and then erase them. |
