Hello all,

I herewith facing some problem in external interrupt, see if anybody 
can suggest me to overrule the difficulty. Hence follows the problem 
description

when i configure my LPC2124 as 

EXTMODE = 0x08; 
...
VICIntEnable = (1<<VIC_EINT3); // Enable external 3

as ISR, i am not getting the interrupt, but when try the same with 
EXT1 its working fine, but i am using both the interrupts in my 
application.
Is it the problem exist in the uC itself or i need to do it in the 
tricky way if so please give me the same code.

rgds,
Lokesh.S

If it does not use an if EXT1,

EXTMODE = 0x0A;

With above try to attempt together.

There is a documented bug in EINT see the errata sheet for workaround
