Memory Address Offset
This register is used to create a virtual image by setting a word offset between the last
address of one line and the first address of the following line. If this register is not equal to
zero, then a virtual image is formed. The displayed image is a window into the larger vir-
tual image. See Figure 8-1: “Screen-Register Relationship, Split Screen,” on page 64.
This register has no effect in SwivelView modes. See “REG[1Ch] Line Byte Count Regis-
ter for SwivelView Mode” on page 69.
