 		 #56423 - RE: Atmel 89C55WD cannot read with MOVC
Responding to: ???'s previous message
"Do you mean that when I lock the chip, I cannot read from code space? If so, I do not believe this is true. Otherwise code would not run."

Never mind just guessing - have you actually read what the Data Sheet has to say on the subject?
