program memory space and the data memory space.
Table Reads and Table Writes have been provided to
move data between these two memory spaces through
an 8-bit register (TABLAT).
The operations that allow the processor to move data
between the data and program memory spaces are:
• Table Read (TBLRD)
• Table Write (TBLWT)

PROGRAM MEMORY
Table Read operations retrieve data from program
memory and place it into the data memory space.
Figure 5-1 shows the operation of a Table Read with
program and data memory.
Table Write operations store data from the data mem-
ory space into program memory. Figure 5-2 shows the
operation of a Table Write with program and data
memory.
Table operations work with byte entities. A table block
containing data is not required to be word aligned, so a
table block can start and end at any byte address. If a
table write is being used to write an executable pro-
gram to program memory, program instructions will
need to be word aligned.
