#140549 - Bootloader v7 and PSEN Responding to: ???'s previous message |
PS. You certainly know the new bootloader from the FM pages, do you? As far as you know, is it possible to use new bootloader v7 from FlashMagic pages and pin PSEN to put the 89V51 into programming mode? This way, it'd be possible somehow to revert to 89C51 behaviour. I read the datasheet and search through the Internet, but I couldn't find anything about this possibility. |
