Hi all, I don't know how many of you are aware, but there seems to be an error in the datasheet. DS39564B is the datasheet in question for the PIC18FXX2 parts. The problem is on P28 table 3-3 the FSR0H is initialised at POR as ----xxxx. If you then look at P46 table 4-2 it is initialised as ----0000 at POR.
