Clearing SNVS Interrupts

Using the Vybrid Security Reference Manual (Rev 1, 5/2013) I've been able to write code to configure and setup SNVS for external and wire-mesh tamper events.  I'm able to force tamper and see the indicated in the SNVS_HPSVSR and SNVS_LPSR.

 

When I enable security violations and setup the interrupts via SNVS_HPSICR and force a tamper event an interrupt will be generated to my software.  How do I clear the SNVS security violation interrupts?  (I've tried writing 0xFFFFFFFF to SNVS_LPSR & SNVS_HPSVSR with no luck.

 

Thanks,

Ryan
