Configure ADC1 to be usable by the ULP This function reconfigures ADC1 to be controlled by the ULP. Effect of this function can be reverted using ``adc1_get_raw()`` function. Note that adc1_config_channel_atten, ``adc1_config_width()`` functions need to be called to configure ADC1 channels, before ADC1 is used by the ULP.
