This bit adds a time offset to the braking portion of the library waveforms. Some motors require more braking time than others, therefore this register allows the user to add or take away brake time from the library waveforms. The most negative voltage value in the library waveform is automatically determined to be the braking portion. This register is only useful in open-loop mode. Braking is automatic for closed-loop mode. The offset is interpreted as 2s complement, therefore the time offset can be positive or negative.
Brake Time Offset (ms) = BRT[7:0] × 5 ms
