Was hoping someone could help me....I'm having trouble getting my multiplication loop working. I have to perform a check to see if the number is out of range (0-255) and if it is branch to either set_zero or set_ff. I'm storing the input variables in a reg x I have in memory. the two numbers are both positive, but blo flag keeps kicking in. the numbers are loading out of memory right. I think it has something to do with the fact that the result of the operation is a 16bit number, stored in the d reg. I tried adding an l in front of the blo, for long word, but that didn't help. all the other functions work as expected. If anyone has any idea, I'd really appreciate it.
