Did you look at the BKRST instruction?

FMOV syntax is as follows: FMOV K0 D0 K100 First item is the source data. Second item is the head address of the destination range. Third item is the number of registers in the destination range. It works very similarly to a BMOV, except that it puts the source data into all of the destination location. You can use a data register for the source data, but it will put that one number in all of the destination locations. FMOV only works on 16-bit devices, so you can't use it on bits unless you group them using the KnMn format. That makes BKRST preferable for bit devices, in my opinion.
