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.
