3. The PERR interrupt bit indicates that MUSYCC detected a parity error during a PCI access cycle. This
Interrupt descriptors can convey certain combinations of events and errors, but no more than one event and one
error. Because multiple information can be conveyed via a single interrupt descriptor, always look at both the event
and error fields when servicing interrupt descriptors. Following is a list of possible combinations of events and
errors.
5.2.5.2.1
The following items are issued separately in their own interrupt descriptors:

In the list below, a single event can combine with a single error within the same interrupt descriptor:

interrupt descriptor being overwritten. Only one bit is overwritten, and the integrity of the original descriptor is
maintained.
condition is conveyed by MUSYCC overwriting the PERR bit field in the last interrupt descriptor in an internal
queue prior to being transferred to shared memory. The bit field is not specific to or associated with the
interrupt descriptor being overwritten. Only one bit is overwritten and the integrity of the original descriptor is
maintained.
