7.3
The TBLRD instruction is used to retrieve data from
program memory and places it into data RAM. Table
reads from program memory are performed one byte at
a time.

The TBLPTR points to a byte address in program
space. Executing TBLRD places the byte pointed to into
TABLAT. In addition, the TBLPTR can be modified
automatically for the next table read operation.
The internal program memory is typically organized by
words. The LSb of the address selects between the high
and low bytes of the word.
Figure 7-4 illustrates the interface between the internal
program memory and the TABLAT.
