4.3.3
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word page of the program space.
This provides transparent access of stored constant
data from the data space without the need to use
special instructions (i.e., TBLRDL/H).
Program space access through the data space occurs if
the Most Significant bit of the data space EA is ‘1’, and
program space visibility is enabled by setting the PSV bit
in the CPU Control register (CORCON<2>). The loca-
tion of the program memory space to be mapped into the
data space is determined by the Program Space Visibil-
ity Page Address register (PSVPAG). This 8-bit register
defines any one of 256 possible pages of 16K words in
program space. In effect, PSVPAG functions as the
upper 8 bits of the program memory address, with the
15 bits of the EA functioning as the lower bits. Note that
by incrementing the PC by 2 for each program memory
word, the lower 15 bits of data space addresses directly
map to the lower 15 bits in the corresponding program
space addresses.
Data reads to this area add an additional cycle to the
instruction being executed, since two program memory
fetches are required.
Although each data space address, 8000h and higher,
maps directly into a corresponding program memory
address (see Figure 4-7), only the lower 16 bits of the
FIGURE 4-7:

24-bit program word are used to contain the data. The
upper 8 bits of any program space locations used as
data should be programmed with ‘1111
‘0000 0000’ to force a NOP. This prevents possible
issues should the area of code ever be accidentally
executed.
For operations that use PSV and are executed outside
a REPEAT loop, the MOV and MOV.D instructions will
require one instruction cycle in addition to the specified
execution time. All other instructions will require two
instruction cycles in addition to the specified execution
time.
For operations that use PSV which are executed inside
a REPEAT loop, there will be some instances that
require two instruction cycles in addition to the
specified execution time of the instruction:
• Execution in the first iteration
• Execution in the last iteration
• Execution prior to exiting the loop due to an
• Execution upon re-entering the loop after an
Any other iteration of the REPEAT loop will allow the
instruction accessing data, using PSV, to execute in a
single cycle.

...while the lower 15
bits of the EA specify
an exact address

This corresponds
exactly to the same
lower 15 bits of the

address.
