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 MS bit 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 2.5, 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 con-
tain 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 3-4), 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 robust-
ness. Refer to the Programmer’s Reference Manual
(DS70030) for details on instruction encoding.

Note that by incrementing the PC by 2 for each pro-
gram memory word, the LS 15 bits of data space
addresses directly map to the LS 15 bits in the corre-
sponding program space addresses. The remaining
bits are provided by the Program Space Visibility Page
register, PSVPAG<7:0>, as shown in Figure 3-4.
For instructions that use PSV which are executed
outside a REPEAT loop:
• The following instructions will require one instruc-
• 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
