7. LOS or OOF Sticky Status Bits May Not Be Cleared
Data Sheet Errata for Product Revision B
LOS or OOF Sticky Status Bits May Not Be Cleared
Description
No individual LOS or OOF sticky status bit may be cleared when any other LOS or OOF alarm is asserted.
Impact
When two or more LOS or OOF sticky status bits are asserted, clearing either one or both requires disabling all the LOS or OOF fault
monitors. LOS and OOF sticky (flag) bits will always remain set whenever asserted. Clearing the sticky bit(s) will have no effect.
Workaround
It is possible to clear a sticky bit by temporarily disabling all LOS and OOF fault monitors. Once disabled, the bit can be cleared and the
fault monitor re-enabled.
Resolution
This erratum will be fixed in the next silicon revision.
