Hi All,

    Seems that LL & SC instrutions operate on a 'word'
    Can we use the same instructions to do a atomic
increment on a 'byte' data. If not, are there any
specific instructions to operate on a byte data?
(Like, LLD & SCD for doubleword data) or else, any 
method to achieve this using the LL & SC instr?

Thanks much,
