 *  @brief      CC26XX/CC13XX implementation of ti/drivers/PWM.h
 *
 *  # Overview #
 *  CC26XX/CC13XX PWM driver using the built-in GPTimer.
 *
 *  # Note #
 *  PWMTimerCC26XX driver calculations for duty cycle are inverted
 *  (for example 25% duty outputs 75%) and output is inverted again in the pad for
 *  correct behavior. This simplifies calculations as period/ timer load value
 *  can be updated independently of duty cycle / match value.
 *
 *  The driver also requires the GPTimer bit GPT.TnMR.TnPLO to be set.
 *  Using this, the PWM output will be always high when load=match and always
 *  low when match>load. Setting match > load is used for 0% duty cycle
