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’.
