There is a documented bug in EINT see the errata sheet for workaround http://www.semiconductors.philips.com/acrobat/erratasheets/2124.pdf

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
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.
