EINT1 and EINT2 problem

2005-01-19 by itsjustimpossible

Hi
Has anyone had a problem when using both EINT1 and EINT2 on the 
LPC2294. I have them assigned to VIC0 and VIC1. (I also have a much 
faster seperate FIQ running.)

If I have both the external interrupts enabled the interrupts stall 
after a few seconds. If I disable one or both, all is well.

I have the same 250uS clock wired to both pins, but EINT1 is 
positive edge triggered and EINT2 is negative edge triggered so I 
can do something on both edges.

Once stalled, if I look in the debugger, both have an interrupt 
pending.

I am using the method suggested in the errata to setup the 
interrupts to avoid corruption of the VPBDIV.

Any suggestions would be gratefully received.

Many thanks
Simon
