K_THERM
The K_THERM register contains the value used by the winding resistance thermal drift
compensation system (see paragraph 7.5).
The available range is from 1 to 1.46875 with a resolution of 0.03125 as shown in Table 7.
9.1.16
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 to rise (see paragraph 9.1.22).
