9.1.13 TOFF_MIN
The TOFF_MIN register contains the minimum OFF time value used by the current control
system (see Section 7.1 on page 33 for details).
The available range for both parameters is from 0.5 µs to 64 µs.
Any attempt to write to the register when the motor is running causes the command to be
ignored and NOTPERF_CMD to rise (see Section 9.1.19 on page 52).
9.1.14 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).
