The current status pins can be used as general purpose input/output ports.
The polarity of the ISx pin is latched when both the top and bottom PWMs are off. At the 0%
and 100% duty cycle boundaries, there is no deadtime, so no new current value is sensed.
Current is sensed even with 0% or 100% duty cycle.

bit, LDOK. Select top/bottom software correction by writing 01 to the current select bits, ISENS[1:0], in the
PWM control register. Reading the IPOLx bits read the buffered value and not necessarily the value
currently in effect.
