FIGURE 3-4:
3.1.2
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
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, as shown in
of the 24-bit program word are used to contain the data.
The upper 8 bits should be programmed to force an ille-
gal instruction to maintain machine robustness. Refer
to the “16-bit MCU and DSC Programmer’s Reference
Manual” (DS70157) for details on instruction encoding.
