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. --- In lpc2000@lpc2..., "lokesh_17" <lokesh_17@y...> wrote:

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