Register 4: PWM Output Inversion (PWMINVERT), offset 0x00C
This register provides a master control of the polarity of the PWM signals on the device pins. The
PWM signals generated by the dead-band block are active High; they can optionally be made
active Low via this register. Disabled PWM channels are also passed through the output inverter (if
so configured) so that inactive channels maintain the correct polarity.
