14.8.22 RQSS – Receive Queue Status
CPU Address:h324
Accessed by CPU, serial interface (RO)
CPU receive queue status
Bit [3:0]: Queue 3 to 0 not empty
Bit [4]: Head of line entry for Queue 0 is valid for too long. CPU Queue 0 has no WRED threshold.
Bit [7:5]: Head of line entry for Queue 3 to 1 is valid for too long or Queue length is longer than WRED
threshold.
14.8.23 TX_AGE – Tx Queue Aging timer
I
2
C Address: h07;CPU Address:h324
Accessed by CPU, serial interface (RW)
Bit [5:0]: Unit of 100ms
(Default 8)
Disable transmission queue aging if value is zero. Aging timer for all ports and queues.
This register must be set to 0 for ‘No Packet Loss Flow Control Test’.

C (R/W)
The MVTX2600 removes the MAC address from the data base and sends a Delete MAC Address Control
Command to the CPU. MAC address aging is enable/disable by boot strap TSTOUT9.
Bit [7:0] Low byte of the MAC address aging timer.
