    Question: My compiler couldn't recognize WDCON.Is WDCON a variable or a register?



    The WDCON is the EICON register, SFR at D8h.  Please see the Technical Reference Manual (version 1.2) of the EZ-USB FX, chapter 2 for further details. The EICON was WDCON in DS80C320 ( Bit Values differ from Reg320).  Make sure you are using the latest development tools.  This has been updated in the framworks header files (ezusb.h and ezreg.c).
