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>).

Preliminary
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.B (Wn<0> = 0)
TBLRDL.B (Wn<0> = 1)
TBLRDL.B (Wn<0> = 0)

• TBLRDH (Table Read High): In Word mode, this
In a similar fashion, 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.
‘Phantom’ Byte
In Byte mode, either the upper or lower byte of the
lower program word is mapped to the lower byte of
a data address. The upper byte is selected when
Byte Select is ‘1’; the lower byte is selected when
it is ‘0’.
instruction maps the entire upper word of a program
address (P<23:16>) to a data address. Note that
D<15:8>, the ‘phantom byte’, will always be ‘0’.
In Byte mode, this instruction maps the upper or
lower byte of the program word to D<7:0> of the
data address, as in the TBLRDL instruction. Note
that the data will always be ‘0’ when the upper
‘phantom’ byte is selected (Byte Select = 1).
