Hi to all engineers.

I need to know more about fsr.
this is what I know.
Fsr is a software register that can hold up to 255 difference values or
registers.
you can store them and you can call them by using INDF instruction.
Am I right?

this is what I do not know.
1. what is the real purpose of this? when do you use it?
2. when you store values how does it organize.

for example.

movlw     0x01
movwf    fsr
movlw    0x02
movwf    fsr
movlw    0x03
movwf    fsr

is this means that fsr (file select register) saved all 3  values or
only the last one?
could you please explaine more.

Andre                        thank you
