2.5
The INDF register is not a physical register. Addressing
the INDF register will cause indirect addressing.
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 register 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 obtained by concatenating the 8-bit FSR register and
the IRP bit (Status<7>) as shown in Figure 2-5.
A simple program to clear RAM locations 20h-2Fh
using indirect addressing is shown in Example 2-2.
