Indirect Addressing, INDF, and FSR Registers
Indirect addressing is a mode of addressing data memory where the data memory address in
the instruction is not fixed. An SFR register is used as a pointer to the data memory location that
is to be read or written. Since this pointer is in RAM, the contents can be modified by the pro-
gram. This can be useful for data tables in the data memory.
indirect addressing. This shows the moving of the value to the data memory address specified
by the value of the FSR register.
Indirect addressing is possible by using the INDF register. Any instruction using the INDF register
actually accesses the register pointed to by the File Select Register, FSR. Reading the INDF reg-
ister itself indirectly (FSR = '0') will read 00h. Writing to the INDF register indirectly results in a
no-operation (although status bits may be affected). An effective 9-bit address is generated by
the concatenation of the IRP bit (STATUS<7>) with the 8-bit FSR register, as shown in
