PIC16(L)F1507
3.2.1
READING PROGRAM MEMORY AS
DATA
There are two methods of accessing constants in
program memory. The first method is to use tables of
RETLW
instructions. The second method is to set an
FSR to point to the program memory.
3.2.1.1
RETLW
Instruction
The RETLW instruction can be used to provide access
to tables of constants. The recommended way to create
such a table is shown in Example 3-1.
EXAMPLE 3-1:
RETLW
INSTRUCTION
The BRW instruction makes this type of table very
simple to implement. If your code must remain portable
with previous generations of microcontrollers, then the
BRW
instruction is not available so the older table read
method must be used.
