The Display Start Address registers form the word address to the display buffer where the
LCD or CRT/TV starts displaying from. An address of 0 points to the beginning of the
display buffer. Changing the start address registers by one pans from 1 to 4 pixels
depending on the current color depth. The following table lists the maximum number of
pixels affected by a change of one to these registers.
