Register Description
Start of Cell Error at UTOPIA Receive Upstream (PHY) Interface
detected.
Unexpected Buffer Error number 2. Should never occur in normal
operation. Immediate reset of the chip is recommended.
Unexpected Buffer Error number 3. Should never occur in normal
operation. Immediate reset of the chip is recommended.
The maximum upstream CDV value for shaped connections given
in CDVU register has been exceeded. This interrupt is a notification
only; that is, no cells are discarded due to this event.
Indicates that a Scheduler Block lost a serving time slot. (Can
indicate a static backpressure on one port).
The ’MUXOV’ interrupt is generated when the number of lost
serving time slots exceeds the number specified in bit field
MaxBurstS(3:0) (see register UECRI/DECRI).
No further action is required upon this interrupt.
Indicates that an interrupt event occurred in the upstream AAL5
unit. The interrupt reason must be read from the AAL5 status
register “UA5SARS/DA5SARS” on Page 172 (upstream).
RM Cell received with corrupted CRC-10.
BIP-8 error detected when reading a cell from the upstream external
SDRAM. BIP-8 protects the cell header of each cell. The cell is
discarded. One single sporadic event can be ignored. Hardware
should be taken out of service when the error rate exceeds 10^-10.
