Table 53 - SDT Reassembly Status Register
Base word address of the last SDT Reassembly Control Structure to generate a
serviceable event (i.e., a status field rollover or bit setting). This field is cleared when the
SDT_RXSAR_STATUS bit in this register is cleared.
SDT RX_SAR Service Enable.
When set, a ‘1’ on SDT_RXSAR_STATUS in this register will cause the
SDT_RXSAR_SRV bit to be set in the Main Status Register at 0002h.
If set, indicates that an unmasked (due to the settings of the Service Enable bits in the SDT
Reassembly Service Enable Register at 2042h) SDT RX_SAR serviceable event has
occurred. Writing a ‘0’ to this bit clears it and clears the SERVICE_ADD field.
SDT RX_SAR Cell Counter Rollover Service Enable.
When set, a ‘1’ on CELL_COUNTER_RO_STATUS in this register will cause the
SDT_RXSAR_SRV bit to be set in the Main Status Register at 0002h.
If set, indicates that the SDT Reassembly Cell Counter Register in register 2048h has
overflowed. Writing a ‘0’ to this bit clears it.
Always reads “0000_0000_0000_00”.
Number of cells received by the SDT RX_SAR.
