PXB 4330
BUFER5
Register Descriptions
Unexpected Buffer Error number 5. Should never occur in normal
operation. Immediate reset of the chip is recommended.
For consistency check the ABM 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.
VCRMER
VC RM Cell received erroneously, when traffic class is configured
for ABR VPs using bit ABRvp TCT1(see Register 13: TCT1).
Note: Several mechanisms are implemented in the ABM to check for consistency of
pointer operation and internal/external memory control. The interrupt events
BUFFER1..BUFFER5 indicate errors detected by these mechanisms.
It is recommended that these interrupts be classified as "fatal device errors."
