PIC18F2480/2580/4480/4580
6.6.3
The use of Indexed Literal Offset Addressing mode
effectively changes how the lower half of Access RAM
(00h to 7Fh) is mapped. Rather than containing just the
contents of the bottom half of Bank 0, this mode maps
the contents from Bank 0 and a user-defined “window”
that can be located anywhere in the data memory
space. The value of FSR2 establishes the lower bound-
ary of the addresses mapped into the window, while the
upper boundary is defined by FSR2 plus 95 (5Fh).
Addresses in the Access RAM above 5Fh are mapped
as previously described (see Section 6.3.2 “Access
Bank”). An example of Access Bank remapping in this
addressing mode is shown in Figure 6-10.
FIGURE 6-10:
DS39637D-page 100
Example Situation:
Locations in the region
from the FSR2 Pointer
(120h) to the pointer plus
05Fh (17Fh) are mapped
to
Access RAM (000h-05Fh).
Special File Registers at
F60h through FFFh are
mapped to 60h through
FFh, as usual.
Bank 0 addresses below
5Fh are not available in
this mode. They can still
be addressed by using the
BSR.

Remapping of the Access Bank applies only to opera-
tions using the Indexed Literal Offset mode. Operations
that use the BSR (Access RAM bit is ‘1’) will continue
to use Direct Addressing as before. Any indirect or
indexed operation that explicitly uses any of the indirect
file operands (including FSR2) will continue to operate
as standard Indirect Addressing. Any instruction that
uses the Access Bank, but includes a register address
of greater than 05Fh, will use Direct Addressing and
the normal Access Bank map.
6.6.4
Although the Access Bank is remapped when the
extended instruction set is enabled, the operation of the
BSR remains unchanged. Direct Addressing using the
BSR to select the data memory bank operates in the
same manner as previously described.
