Any attempt to write to the register when the outputs are enabled causes the command to
be ignored and the NOTPERF_CMD to rise (see Section 9.1.13).
9.1.7 TOFF_MIN
The TOFF_MIN register contains the minimum OFF time value used by the current control
system (see Section 7.1 for details).This parameter imposes the OFF time of the current
control system only if its value is greater than the TSW one.
The available range for both parameters is from 0.5 µs to 64 µs.
Any attempt to write to the register when the outputs are enabled causes the command to
be ignored and the NOTPERF_CMD to rise (see Section 9.1.13).
