Function Documentation

initEPWM_aux_trip()

void initEPWM_aux_trip	(	uint32_t	aux_pwm_base,
		EPWM_DigitalCompareTripInput	system_trip_source,
		uint16_t	trip_delay
	)

Defines the initialization steps for an auxiliary PWM output.

Another EPWMxA will be used as auxiliary trip signal for inner switches, with the dead-band insertion for the auxiliary PWM action at the system trip event.

Parameters

aux_pwm_base	PWM base register for the auxiliary PWM output
system_trip_source	Trip input for the system trip event
trip_delay	Customized delay timing with rising edge delay

Returns

None

configEPWMDelayTrip()

void configEPWMDelayTrip	(	uint32_t	base1,
		EPWM_DigitalCompareTripInput	aux_trip_source
	)

Configures the delay trip action for inner switches(PWMxB).

Parameters

base1	PWM base register for inner switches
aux_trip_source	Trip input for the auxiliary PWM output

Returns

None
