6.0
In PIC18F2X1X/4X1X devices, the program memory is
implemented as read-only Flash memory. It is readable
over the entire V
read from program memory is executed on one byte at
a time.
6.1
For PIC18 devices, there are two operations that allow
the processor to move bytes between the program
memory space and the data RAM: table read (TBLRD)
and table write (TBLWT).
Table read operations retrieve data from program
memory and place it into the data RAM space.
Figure 6-1 shows the operation of a table read with
program memory and data RAM.
The program memory space is 16 bits wide, while the
data RAM space is 8 bits wide. Table reads and table
writes move data between these two memory spaces
through an 8-bit register, TABLAT.

Program Memory
Table reads work with byte entities. A table block
containing data, rather than program instructions, is not
required to be word-aligned. Therefore, a table block can
start and end at any byte address.
Because the program memory cannot be written to or
erased under normal operation, the TBLWT operation is
not discussed here.

2: The TBLWT instruction is available only in
PIC18F2X1X/4X1X devices in normal
operation, the TBLWT instruction is still
implemented in the instruction set.
Executing the instruction takes two
instruction cycles, but effectively results
in a NOP.
