-/* The ADC input clock is generated from PCLK2/APB2 divided by a prescaler
- * and it must not exceed 14MHz.
- *
- * ADC1 and ADC2 are clocked by APB2
- *
- * 1) Power on by setting ADON in ADC_CR2
- * Conversion starts when ADON is set for a second time after some
- * time t > t_stab.
- *
- * Up to 16 selected conversion must be selected in ADC_SQRx
- *
- * Single conversion mode:
- * Set the ADON bit in the ADC_CR2 register
- * Once the conversion is complete:
- *  Converted data is stored in ADC_DR
- *  EOC flag is set
- *  Interrupt is generated if EOCIE is set
- *
- * Calibration:
- * Calibration is started by setting the CAL bit in the ADC_CR2 register.
- * Once calibration is over, the CAL bit is reset by hardware and normal
- * conversion can be performed. Calibrate at power-on.
- *
- * ALIGN in ADC_CR2 selects the alignment of data
- *
- * IMPORTANT: maximum external impedance must be below 0.4kOhms for 1.5
- * sample conversion time.
- *
- * At 55.5 cycles/sample, the external input impedance < 50kOhms*/
