I am trying to use the ISP bootloader on the Philips P89C51RC2Hxx. I am looking for any information on what I have to do to my code to get it to work. For my hardware, I have EA tide high and a jumper on PSEN that allows me to pull it low. I intend to use the default bootloader located at 0xFC00. I have the FlashMagic utility for communicating with my board. Steve
all that basically says is that if you use RC reset you are in trouble, use a watchdog. Happy new year Erik
