The core has two data spaces. The data spaces can be
considered
instructions), or as one unified linear address range (for
MCU instructions). The data spaces are accessed
using two Address Generation Units (AGUs) and
separate data paths.

PSVPAG is an 8-bit register, containing bits <22:15> of the program space address (i.e., it defines
the page in program space to which the upper half of data space is being mapped).

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.
