ADS8168: The sdo doesn't get the expected output.

Hello ，

     ADS816x 8-Channel, 16-Bit, 1MSPS, SAR ADC With Direct Sensor Interface datasheet (Rev. D)

    On power-up, ADS8168 is already configured to manual mode.

    please configure the CHANNEL_ID register to select which channel sample to take.

     This data is then clocked out on SDO after 2 cycles.

According to the chip manual, the AD chip will be configured into manual mode after power-on, check the 0 channel.

I have tried to power on without configuring any registers, and directly access the analog signal to channel 0, but the SDO did not give any response, I am not sure about the situation after changing the channel, wait for me to try.

After powering up, the mode is manual mode, the channel is AIN0, I tried to connect the analog signal directly to AIN0 without configuring any registers, but the SDO does not send back data.I'll try to configure the  the CHANNEL_ID register.
