1) In 8051, how one can do multibyte subtraction if the
subtrahend's lower byte has greater than the minuend lower byte for ex 5F82-30FF with SUBB instruction ( when you subtract FF from 82 you will get CY=? and 2's complement) 2) In PACKED BCD addition what you do when both bytes are greater than 09 (i.e) 68+34 with DA instruction |
