BUFER4
Data Sheet
Note: Several mechanisms are implemented in the ABM-3G to check for consistency
of pointer operation and internal/external memory control. The interrupt events
BUFER1..BUFER4 indicate errors detected by these mechanisms.
It is recommended that these interrupts be classified as "fatal device errors."
Unexpected Buffer Error number 4. Should never occur in normal
operation. Immediate reset of the chip recommended.
For consistency check the ABM-3G stores the queue ID with each
cell written to the respective queue within the cell storage RAM.
When reading a cell from the cell storage RAM, the queue ID is
compared to the stored queue ID.
A queue ID mismatch would indicate a global buffering/pointer
problem.
