[TI-H] Re: Carlos Becker....question about PIC code?
F is used throughout the instruction set to refer to a specified file
register.
The f in "decfsz" refers to this register, the source argument for all
instructions is called f because it specifies which file register this
is.
The destination is either F (the File register that was used as the
source), or W (the Working register)
So that's why F is used instead of the binary value, it's easier to
remember. (I hope that's what you were asking...)
for the actual instruction encoding, W=0; F=1
