    I think it is sort of interesting that in both the PIC18F47J53, and the PIC18F46J50 (both known to work with PBP USB) it states:
    Note: The SFRs located between EB0h and
    F5Fh are not part of the Access Bank.
    Either BANKED instructions (using BSR) or
    the MOVFF instruction
    should be used to
    access these locations. When programming
    in MPLAB® C18, the compiler will
    automatically use the appropriate
    addressing mode.
    However, for the PIC18F67J50, they leave the MOVFF part out of this statement. I wonder if Microchip knows its errata and just didn't add it to the errata list. Or it's just a coincidence.
