Register Description
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 recommended.
The maximum downstream 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 downstream AAL5
unit. The interrupt reason must be read from the AAL5 status
register “UA5SARS/DA5SARS” on Page 210 (downstream).
RM cell received with corrupted CRC-10.
BIP-8 error detected when reading a cell from the downstream
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.
