9.3 Arbiter Registers
80 of 169
The Arbiter manages the transport between the Ethernet port and the Serial Interface. It is responsible for queuing
and dequeuing data to an external SDRAM. The arbiter handles requests from the HDLC and MAC to transfer
data to/from the SDRAM. The base address of the Arbiter register space is 0040h.

Bits 0-7: Receive Queue Size (RQSC[0:7])
These 7 bits of the size of receive queue associated with the
connection. Receive queue is for data arriving from the MAC to be sent to the WAN. The Queue address size is
defined in increments of 32 x 2048 bytes. The queue size is AR.RQSC1 multiplied by 32 to determine the number
of 2048 byte packets that can be stored in the queue. This queue is constructed in the external SDRAM
. Note:
Queue size of 0 is not allowed and should never be set.

Bits 0-7: Transmit Queue Size (TQSC[0:7])
This is size of transmit queue associated with the connection. The
queue address size is defined in increments of 32 packets. The range of bytes will depend on the external SDRAM
connected to the DS33Z11. Transmit queue is the data queue for data arriving on the WAN that is sent to the
MAC.
Note that queue size of 0 is not allowed and should never be set.
