From page 101 of the datasheet (rev DS40300C):<BR>
&quot;When an interrupt is responded to, the GIE is cleared to disable any further interrupt&quot;.  Therefore, when you have finished servicing your interrupt, you must set the GIE bit again.  This may be the reason you only see the interrupt serviced once.
