 		 #73369 - RE: p89v51rd2 secutity bit - serial number
Responding to: ???'s previous message
If I program serial number and leave the security bit unprogrammed (to update program in the uture),code can be recovered via parallel programmer?
Any parallel programmer (I know of) with an entry for the chip you use can read the chip if security is not set.
