This register forms the 20-bit address for the starting word of the CRT/TV image in the
display buffer. Note that this is a word address. An entry of 00000h into these registers
represents the first word of display memory, an entry of 00001h represents the second
word of the display memory, and so on.

These bits are the CRT/TV display's 11-bit address offset from the starting word of line
"n" to the starting word of line "n + 1". A virtual image can be formed by setting this
register to a value greater than the width of the display. The displayed image is a window
into the larger virtual image.
