2.0 FUNCTIONAL DESCRIPTIONS

2.1.1 INDF (Indirect Addressing Register)
Address
Name
00h (r/w)
INDF
The INDF Register is not a physical register. Any instruction accessing the INDF register can actually access the
register pointed by FSR Register. 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).
The bits 5-0 of FSR register are used to select up to 64 registers (address: 00h ~ 3Fh).
In FM8P51 series, the data memory is partitioned into four banks. Switching between these banks requires the RP1
and RP0 bits in the FSR register to be configured for the desired bank. The lower locations of each bank are
reserved for the Special Function Registers. Above the Special Function Registers are General Purpose Registers.
All Special Function Registers and some of General Purpose Registers from other banks are mirrored in bank 0 for
code reduction and quicker access.

EXAMPLE 2.1: INDIRECT ADDRESSING
Register file 38 contains the value 10h
Register file 39 contains the value 0Ah
Load the value 38 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=39h)
A read of the INDR register now will return the value of 0Ah.
