Lpc2000

Hello my friends!

I\ufffdm using something similar it!
first u need clear all interrupts, so u will set
extpolar and extmode.

see it!
it work very well with my program test!


   VICIntEnClear   = 0xFFFFFFFF;
   VICSoftIntClear = 0xFFFFFFFF;
   EXTPOLAR_bit.EXTPOLAR0 = 0x00;
   EXTMODE_bit.EXTMODE0   = 0x00;  
   EXTINT_bit.EINT0 = 0x00;

I am using LPC2214. A few months ago I have the same
problem. What I
found is that you are going to face problems not only
with VPBDIV if
you do reconfigure EINT mode. But with all the
consecutive writings to
the any of the VPB peripheral registers. There was not
problem with
the registers of VIC which belongs to AHB peripherals.
I try to use the recommended workaround but with
partial success. I
did not succeed to reconfigure EINT0.
Now I use EINT0 in the default mode as Ken Wada
suggested too.
If you need External Interrupt with dynamically
configured mode there
was a post in this group with the idea to use IRQ of a
Capture of a
Timer if you have a free one.
