LCD & VGA Controllers
11.15 Video Controller Register Locations
The VideoControl register appears in two positions in the register map. It appears in the LCD
area and also in the VGA area. This register allows both controllers to be enabled
simultaneously. The LCD and VGA palette registers can also be read and written in their own
unique address space, or written only in a combined area.
Table 11-15: LCD register map locations shows the registers associated with the LCD
controller and the physical addresses used to access them.
