Indirect Data Addressing; INDF and
FSR Registers
The INDF register is not a physical register.
Addressing INDF actually addresses the register
whose address is contained in the FSR register (FSR
is a pointer). This is indirect addressing.
EXAMPLE 4-1:
Register file 07 contains the value 10h
Register file 08 contains the value 0Ah
Load the value 07 into the FSR register
A read of the INDF register will return the value
of 10h
Increment the value of the FSR register by one
(FSR = 08)
A read of the INDR register now will return the
value of 0Ah.
INDIRECT ADDRESSING
Reading INDF itself indirectly (FSR = 0) will produce
00h. Writing to the INDF register indirectly results in a
no-operation (although STATUS bits may be affected).
A simple program to clear RAM locations 10h-1Fh
using indirect addressing is shown in Example 4-2.

The FSR is a 5-bit wide register. It is used in
conjunction with the INDF register to indirectly address
the data memory area.
The FSR<4:0> bits are used to select data memory
addresses 00h to 1Fh.
PIC12C508/PIC12C508A/PIC12CE518:
Does not
use banking. FSR<7:5> are unimplemented and read
as '1's.
PIC12C509/PIC12C509A/PIC12CR509A/
PIC12CE519:
Uses FSR<5>. Selects between bank 0
and bank 1. FSR<7:6> is unimplemented, read as '1’ .
