Any attempt to write to the register when the motor is running causes the command to be
ignored and NOTPERF_CMD to rise (Section 11.1.28).
11.1.18 TON_MIN
This register is specific for current mode driving (see Section 9).
This parameter is used by the current control system when current mode operation is
selected.
The TON_MIN register contains the minimum on-time value used by the current control
system (see Section 9.2).
The available range for both parameters is from 0.5 μs to 64 μs.
