SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
RWB:
This bit is used to indicate whether the user is writing the setup of a FIFO, or reading all setup
information of a FIFO. This bit is used in conjunction with the BUSY bit. When this bit is set
to 1, all the available setup information of the FIFO requested in PHYID[5:0] is available in
the registers RXSDQ FIFO Indirect Configuration, RXSDQ FIFO Indirect Buffer Available
Threshold, RXSDQ FIFO Indirect Data Available Threshold, and RXSDQ FIFO Indirect Cells
and Packets Count. When this bit is set to 0, the user is writing the configuration of a FIFO.
BUSY:
This is a read-only bit is used to indicate to the user that the information requested for the
FIFO specified in bits PHYID[5:0] is in the process of being updated. If this bit is sampled to
be 1, the update is still in progress. If this bit is sampled 0, the information for the FIFO is now
available in the accessed register.
