FSR Registers and the
INDF Operand
At the core of Indirect Addressing are three sets of
registers: FSR0, FSR1 and FSR2. Each represents a
pair of 8-bit registers, FSRnH and FSRnL. The four
upper bits of the FSRnH register are not used, so each
FSR pair holds a 12-bit value. This represents a value
that can address the entire range of the data memory
in a linear fashion. The FSR register pairs, then, serve
as pointers to data memory locations.
Indirect Addressing is accomplished with a set of Indi-
rect File Operands, INDF0 through INDF2. These can
be thought of as “virtual” registers: they are mapped in
the SFR space but are not physically implemented.
Reading or writing to a particular INDF register actually
accesses its corresponding FSR register pair. A read
from INDF1, for example, reads the data at the address
indicated by FSR1H:FSR1L. Instructions that use the
INDF registers as operands actually use the contents
of their corresponding FSR as a pointer to the instruc-
tion’s target. The INDF operand is just a convenient
way of using the pointer.
Because Indirect Addressing uses a full 12-bit address,
data RAM banking is not necessary. Thus, the current
contents of the BSR and the Access RAM bit have no
effect on determining the target address.

Using an instruction with one of the
Indirect Addressing registers as the
operand....
...uses the 12-bit address stored in
the FSR pair associated with that
register....
...to determine the data memory
location to be used in that operation.
In this case, the FSR1 pair contains
FCCh. This means the contents of
location FCCh will be added to that
of the W register and stored back in
FCCh.
