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.
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).
The FSR is an 8-bit wide register. It is used in conjunc-
tion 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.
FSR<5> is used to select between banks (
0
= Bank 0,
1
= Bank 1).
FSR<7:6> are unimplemented and read as ‘
11
’.
