9.4.2 Receive Channel Statistics Block
Base address: 610000h (0184000h byte)
Index: 4h
The long address = 610000h + RX_CHAN_NUM × 4h+ long_offset
The receive channel statistics counters are only valid if the RX_STATS bit in the
RX_QUEUE_ENGINE_TEST register (“RX_QUEUE_ENGINE_TEST” on
page 123) is set to 1

9.5 SDRAM/SGRAM Interface Description
The SDRAMs/SGRAMs are used in the QRT system to store the cells in the receive and transmit
directions. Before the SDRAMs/SGRAMs can be used, they must be prepared for operation. This
section discusses setting up the SDRAM/SGRAM for normal operations, as well as test mode
access by the microprocessor to check the data integrity of the SDRAM/SGRAM.
