The upper 32 Kbytes of data space may optionally be
mapped into any 16K word program space page. This
provides transparent access of stored constant data
from X data space, without the need to use special
instructions (i.e., TBLRDL/H, TBLWTL/H instructions).
Program space access through the data space occurs
if the MSb of the data space EA is set and program
space visibility is enabled, by setting the PSV bit in the
Core Control register (CORCON). The functions of
CORCON are discussed in Section 2.4 “DSP
Engine”.
Data accesses to this area add an additional cycle to
the instruction being executed, since two program
memory fetches are required.
Note that the upper half of addressable data space is
always part of the X data space. Therefore, when a
DSP operation uses program space mapping to access
this memory region, Y data space should typically
contain state (variable) data for DSP operations,
whereas X data space should typically contain
coefficient (constant) data.
Although each data space address, 0x8000 and higher,
maps directly into a corresponding program memory
address (see Figure 3-5), only the lower 16 bits of the
24-bit program word are used to contain the data. The
upper 8 bits should be programmed to force an illegal
instruction to maintain machine robustness. Refer
to the
Manual” (DS70157) for details on instruction encoding.

Note that by incrementing the PC by 2 for each
program memory word, the Least Significant 15 bits of
data space addresses directly map to the Least
Significant 15 bits in the corresponding program space
addresses. The remaining bits are provided by the
Program Space Visibility Page register, PSVPAG<7:0>,
as shown in Figure 3-5.
For instructions which use PSV that are executed
outside a REPEAT loop:
• The following instructions will require one
• All other instructions will require two instruction
For instructions that use PSV which are executed
inside a REPEAT loop:
• The following instances will require two instruction
• Any other iteration of the REPEAT loop will allow
