4.6.2
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going
through data space. The TBLRDH and TBLWTH
instructions are the only method to read or write the
upper 8 bits of a program space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to data space addresses.
Program memory can thus be regarded as two 16-bit
wide word address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space that contains the least significant
data word. TBLRDH and TBLWTH access the space that
contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operations.
• TBLRDL (Table Read Low):

- In Word mode, this instruction maps the
lower word of the program space location
(P<15:0>) to a data address (D<15:0>).

The address for the table operation is determined by the data EA
within the page defined by the TBLPAG register.
Only read operations are shown; write operations are also valid in
the user memory area.

• TBLRDH (Table Read High):
Similarly, two table instructions, TBLWTH and TBLWTL,
are used to write individual bytes or words to a program
space address. The details of their operation are
explained in Section 5.0 “Flash Program Memory”.
For all table operations, the area of program memory
space to be accessed is determined by the Table Page
register (TBLPAG). TBLPAG covers the entire program
memory space of the device, including user and
configuration spaces. When TBLPAG<7> = 0, the table
page is located in the user memory space. When
TBLPAG<7> = 1, the page is located in configuration
space.
