 		 #98236 - my lengthy posts are boring
Responding to: ???'s previous message
I should write more briefly :-)

It's at the beginning of my previous post - RD2s do use PSEN fot ISP entry. The exception is the P89V51RD2(and the corresponding SST part) which simply enters the bootcode upon each reset.
