7. 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.
