    Wink Not all CPU freq are available ....

    Hi, Bonxy

    the Question is ...

    Which freq do you want to run the CPU ??? ... here we just know you use a 20 Mhz external XTAL ...

    BUT which is YOUR " CPUDIV_OSCx_PLLy _1L setting ???


    note you can't run the CPU@ 20 Mhz ... using PLL and USB ( 16 or 24 Mhz only - PLL x4 or x6 ... ).
    The ONLY available CPU freq are 48, 32, 24 and 16 Mhz, when using USB

    20Mhz need using only HS oscillator ... no USB then !!!

    Soooo ... nothing strange ...

    Try 24 Mhz ... and do not forget the " DEFINE "...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
