The voltage spikes on Rsense could be filtered by selecting an appropriate blanking time on

the output of current sense comparator. The Blanking time selection is made by using the

StepBlkTime[1:0] bits in the StpCfg1 register.

The stepper driver off time could be programmed by means of the StepOffTime[4:0] bits in

StpCfg1 register.
