Base_scale

Used to alter the value of the register contents, after masking, to define the actual base. If the number is positive, it is multiplied against the register content. If the number is negative, it is divided from the register content. For example, a byte register might select the 64Kbyte region to map to. If the scale is 0x10000 (64K), then register values of 0, 1, 2, 3,... each select a 64Kbyte region. If the selector occupies part of a register, the mask is applied to select only the selector portion and the scaling value itself might be scaled. Using the example above, if the byte selector portion is the upper byte of a register, the scale value is 0x10000/0x100=0x100 (256). So, mask with 0xFF00 and multiply by 256 to get a 64Kbyte selection.
