on data transferred into MUSYCC either from another PCI agent
writing into MUSYCC, or from MUSYCC reading data from shared
memory. This error is specific to the data phase of a PCI transfer while
MUSYCC is receiving data. Note: PCI system error signal, SERR*, is
ignored by MUSYCC. NOTE: To mask the PERR interrupt, MUSYCC’s

Interrupt Lost. Generated when internal interrupt queue is full, and
additional interrupt conditions are detected. Because MUSYCC cannot
store the newest interrupt descriptors, it discards the new interrupts
and overwrites this bit in the last interrupt in an internal queue prior to
that interrupt being transferred out to shared memory. The integrity of
the descriptor being overwritten is maintained.
