VicIntEnable Register of LPC2148

[Twisted_transistor]

Hi.. I urgently want to know the configuration of the VicIntEnable Register of LPC2148. I've searched everywhere but in vain. Can someone pls help? Need it for my final year project.

Thank you. Muito obrigada

As they say, when everything else fails check the manual...

Did you read chapter 7?


Also download the The Insider's Guide To The NXP LPC2000 and check section 3.12

Thanks alot Alex. I found the register configuration but the use of VICIntEnClr register to disable the UART1 interrupt still does not work. Could you pls check my code and tell me why?
Thanks.
