Motor constrained state detection output
(This is an open-collector output.)
When the motor is constrained: high, when the motor is
turning: low.
PWM pulse input.
When low the output will be on and when high or open
the outputs will be off. If this pin is used to control this IC,
connect EI- to ground and connect EI+ to TOC.
Start/stop control. Low: start, high or open: stop.
CTL amplifier noninverting input
CTL amplifier inverting input
PWM waveform comparator (CTL amplifier output)
