Lpc2000

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.
