    evident that without the power error codes are different. without supplying power to vccq error code is changed to (ERR [0071], POS [0001]) found no fault description for the riff Boxing
    This logic analyzer I have removed the data from the line

    cmd lift lines and D0 is made of 100 ohm resistor to VCC. vddi capacitor between the ground and standing on a 1 uF. supply voltage is taken from the box. Connect is about 20-30 seconds and pops up an error.
