I have RB <7:4> set up as interrupts (I am using a 16C84),  If I leave
those pins open (not connected) then the program runs through as if the
interrupts occurred.  If I put one of the pins to ground the it stops
this (because the program waits for all interrupts to complete before
continuing).

The problem is that I can not leave these pins grounded all the time
because I have a external device connected to it.  When the device is
connected it goes through the interrupts despite what the device is
clock (setting the interrupts at).


Any suggestions

Thanks
John
