9.1.8 ADC_OUT
The ADC_OUT register contains the result of the analog to digital conversion of the ADCIN
pin voltage.
Any attempt to write to the register causes the command to be ignored and the
NOTPERF_CMD flag to rise (see Section 9.1.13).
9.1.9 OCD_TH
The OCD_TH register contains the overcurrent threshold value (see Section 6.9 for details).
The available range is from 375 mA to 6 A, steps of 375 mA as shown in Ta bl e 1 7.
