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.
