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 3-6), 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 “dsPIC30F/33F Programmer’s Reference Manual”
(DS70157) for details on instruction encoding.
