Mark a flag that says "interrupt pending" somewhere and return.</SPAN><BR /><SPAN>2. in my main code set the endpoint interrupt flag using USBDevIntSet register. This will cause the event to re-trigger.</SPAN><BR /><BR /><SPAN>And something that caught me... USBDevIntSet is a write only register so don't |= your bit in.</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 16:57:46 GMT https://community.nxp.com/t5/LPC-Microcontrollers/USB-Bulk-interrupt-re-triggering/m-p/525832#M8468 lpcware 2016-06-15T16:57:46Z
