BUFER4
ABM-P
PXF 4336 V1.1
Register Description
Unexpected Buffer Error number 4. Should never occur in normal
operation. Immediate reset of the chip recommended.
For consistency check the ABM-P 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.
VPRMER
VP RM Cell received erroneously when traffic class is configured for
VCs using bit ABRvp in Register TCT3
(see Register 42: TCT3).
Note: Several mechanisms are implemented in the ABM-P 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."
