MQX usb Device stack Vbus ISR Configuration

Question asked by pankaj kharche on Apr 2, 2014



I have used the mqx usb device stack for my usb application. I have used IRQ6 pin interrupt to detect vbus attached event , with the help of mqx gpio example code of mcf54418 stack.


My question is that,

When I am plugging In usb connector, the interrupt comes and control goes to ISR function but it continuously cal ISR after i have removed usb connector. I have set  EPFR resigister bit in ISR using till no effect.


Where should i am wrong? Which register I have to configure in ISR so that ISR cal only one time.
