NOTE:

Because of the true 4 quadrant method of output switching,

the output switches will PWM between the ICOMMAND POSITIVE

and ICOMMAND NEGATIVE states, with the average percentage

based on ICOMMAND being a positive voltage and a negative

voltage. With a zero voltage ICOMMAND, the output switches will

modulate with exactly a 50% duty cycle between the

ICOMMAND POSITIVE and ICOMMAND NEGATIVE states.
