 		 #182962 - Serial EEPROM
Responding to: ???'s previous message
Hi Andy,


As far as data access time is concern it is ok, But it is also slowing down your processing speed as instruction and data accesses are serialized. In some, not all applications where margin is very narrow this might be an issue.
