The upper 32 Kbytes of data space may optionally be
mapped into an 8K word page (in PIC24F08KA1XX
devices) and a 16K word page (in PIC24F16KA1XX
devices) 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 MSb of the data space EA is ‘1’, and PSV is
enabled by setting the PSV bit in the CPU Control
(CORCON<2>) register. The location of the program
memory space to be mapped into the data space is
determined by the Program Space Visibility Page
Address register (PSVPAG). This 8-bit register defines
any one of 256 possible pages of 16K words in pro-
gram 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.
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 from this area add an additional cycle to the
instruction being executed, since two program memory
fetches are required.

Program Space
The address for the table operation is determined by the data EA
within the page defined by the TBLPAG register. Only read
operations are provided; write operations are also valid in the
user memory area.
TBLRDH.B (Wn<0> = 0)
TBLRDL.B (Wn<0> = 1)
TBLRDL.B (Wn<0> = 0)
TBLRDL.W
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
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
