• Manufacturer: Freescale Semiconductor, Inc

Setting the OUTCTLx bits do not disable the PWM generators and current status sensing circuitry. They
continue to run, but no longer control the output pins. When the OUTCTLx bits are cleared, the outputs of
the PWM generator become the inputs to the deadtime generators at the beginning of the next PWM cycle.
Software can drive the PWM outputs even when PWM enable bit (PWMEN) is set to zero.
Freescale Semiconductor
Avoid an unexpected deadtime insertion by clearing the OUTx bits before
setting and after clearing the OUTCTLx bits.
