#139699 - compare two values, jump if greater or equal |
Just wondering how to compare two bytes, and jump if greater or equal.
I know that this command exists in the avr's, but I haven't found a way to do it on 8051. I want to compare DPH with value 75h, if result is equal or higher than 75h, jump to a routine. I know about cjne, but I don't really care if it is equal, just higher.
mov a,dph
cjne a,#075h,Next ;the dph byte may not equal 75, it may be
;an unknown value higher than 75
sjmp blah blah blah...
Next:
blah blah blah...
anyone with any ideas?, links? I tried searching but too many answers, nothing specific to what I am looking for. |
