K_THERM
The K_THERM register contains the value used by the winding resistance thermal drift
compensation system (see Section 7.6 on page 37).
The available range is from 1 to 1.46875 with a resolution of 0.03125, as shown in Table 13.

ADC_OUT
The ADC_OUT register contains the result of the analog-to-digital conversion of the ADCIN
pin voltage; the result is available even if the supply voltage compensation is disabled.
Any attempt to write to the register causes the command to be ignored and the
NOTPERF_CMD flag to rise (see Section 9.1.22 on page 55).
