3.2
The core has two data spaces. The data spaces can be
considered either separate (for some DSP instructions),
or as one unified linear address range (for MCU instruc-
tions). The data spaces are accessed using two Address
Generation Units (AGUs) and separate data paths.
3.2.1
The data space memory is split into two blocks, X and
Y data space. A key element of this architecture is that
Y space is a subset of X space, and is fully contained
within X space. In order to provide an apparent Linear
Addressing space, X and Y spaces have contiguous
addresses.

X Data
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 3-7.
