Thanks Richard actually i wanted to avoid any Interrupt routine. anyway, i think i can use other interrupt status register bits also without enabling them. regards Manisha. -----Original Message----- From: lpc2000@yahoogroups.com [mailto:lpc2000@yahoogroups.com]On Behalf Of Richard Duits Sent: Saturday, March 04, 2006 5:42 PM To: lpc2000@yahoogroups.com Subject: Re: [lpc2000] Polling for data reception I don't know anything about the USB controller, because I never used an LPC214x. All I know that you can poll if an interrupt routine would be called if you enabled the interrupt, by reading the VICRawIntr register. Regards, Richard.
