The PIC on the RC has a bootloader on it. There's read/write commands as well as a few other things. The IFI bootloader is a slightly modified version of the one put out by Microchip. Matt Fowler (FRC team #312) sent me a whitepaper on the IFI bootloader. The Microchip bootloader has the same protocol and both share most of their commands. For documentation on the Microchip bootloader, look for AN851 on their website.
