5.6.1
Enabling the PIC18 extended instruction set changes
the behavior of Indirect Addressing using the FSR2
register pair and its associated file operands. Under the
proper conditions, instructions that use the Access
Bank – that is, most bit-oriented and byte-oriented
instructions – can invoke a form of Indexed Addressing
using an offset specified in the instruction. This special
addressing mode is known as Indexed Addressing with
Literal Offset, or Indexed Literal Offset mode.
When using the extended instruction set, this
addressing mode requires the following:
• The use of the Access Bank is forced (‘a’ = 0);
• The file address argument is less than or equal to
Under these conditions, the file address of the
instruction is not interpreted as the lower byte of an
address (used with the BSR in Direct Addressing) or as
an 8-bit address in the Access Bank. Instead, the value
is interpreted as an offset value to an Address Pointer
specified by FSR2. The offset and the contents of
FSR2 are added to obtain the target address of the
operation.

5.6.2
Any of the core PIC18 instructions that can use Direct
Addressing are potentially affected by the Indexed Literal
Offset Addressing mode. This includes all byte-oriented
and bit-oriented instructions, or almost half of the
standard PIC18 instruction set. Instructions that only use
Inherent or Literal Addressing modes are unaffected.
Additionally, byte-oriented and bit-oriented instructions
are not affected if they use the Access Bank (Access
RAM bit is ‘1’) or include a file address of 60h or above.
Instructions meeting these criteria will continue to
execute as before. A comparison of the different possible
addressing modes when the extended instruction set is
enabled is shown in Figure 5-10.
Those who desire to use byte-oriented or bit-oriented
instructions in the Indexed Literal Offset mode should
note the changes to assembler syntax for this mode.
This is described in more detail in Section 25.2.1
“Extended Instruction Syntax”.
