When executing any instruction other than one of the
MAC class of instructions, the X block consists of the 64-
Kbyte data address space (including all Y addresses).
When executing one of the MAC class of instructions,
the X block consists of the 64-Kbyte data address
space excluding the Y address block (for data reads
only). In other words, all other instructions regard the
entire data memory as one composite address space.

The MAC class instructions extract the Y address space
from data space and address it using EAs sourced from
W10 and W11. The remaining X data space is
addressed using W8 and W9. Both address spaces are
concurrently accessed only with the MAC class
instructions.
The data space memory map is shown in Figure 3-6.
