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 9.1.19).
9.1.15
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 Table 17.
