Pwm Choping and trip

Question asked by binki on May 23, 2013

I have few clarifications in ADSP-BF609 Pwm module. Can anyone help on this?


What is Pwm frequency chopping?


If chopping is enabled for channel A will duty cycle get varied according to chop frequency?


If trip is enabled, then can we give active high pulse from any of the high pins?

If trip occurs will all the channels gets shut down?



If Cross over function is enabled for channel A and if only PWM_AH channel is configured, then will

PWM_AH output goes to PWM_AL? and PWM_AL is not configured so what pulse will come on PWM_AH? Is it active low pulse?



Thanks in advance.
