Well, Jinx is a PIC genius, that's not in doubt.
BUT I do have to question the logic behind adding
nops to a RMW, if you can afford one or more
instructions timewise why not just movf,w then
movwf PORT and write to the entire port??
Or is there some esoteric benefit to clinging to
a bsf PORT,x when you have cycles to spare??
