All,

 Is it possible to impliment a jump table based on the value read from an IO 
port?
What I want is to have a 8 routines, and when the value from a port is read 
(3 bit value) it jumps to the appropriate routine, I want to avoid CMP and 
BREQ if possible as I need a constant length for this, using multiple 
CMP/BREQs would result in a variable excution time.

Oh, I'm doing this in assembler....

Any thoughts?
