    TLE7242 dither waveform problem

    Hi all,

    I can set and see differences betwen old and new setpoint value, KP/KI value, Main Freq,
    But, when I set dither value (Msg#3, Msg#4), and enable dither (Msg#3), I could not see difference between old and new curve, curve is seen the same on the oscilloscope screen.
    Also I set different values to see dither wave, but I cannot.

    Do you know why? and Could you send me curve shot with dither and wthout dither?


    example used data is below what I used;

    cyristal (SCK): 40MHz
    Main period set (Msg#1) : 1250 , 1kHz is ok
    setpoint value : 245 -> 319mA // it is ok
    dither step size(Msg#3) : 15
    dither enable(Msg#3) : 1
    Dither period set (Msg#4) : 4

    spi sending data(Msg#3) : 0x8C80F8F5
    spi sending data(Msg) :0x90000004
    spi clk: 10MHz

    Thank you for your help,

    BR
