PHYDEV[4:0]:  
The PHYDEV[4:0] bits are used to define the polling range of the SCI-  
PHY/Any-PHY input port when configured as a bus master (IMASTER is set  
to logic 1) The number of PHY devices to be polled is configured as follows:  
PHYDEV[4:0]  
00000  
00001  
00010  
00011  
:
Description  
Poll all 32 devices  
Poll PHY#1 thru PHY#2  
Poll PHY#1 thru PHY#3  
Poll PHY#1 thru PHY#4  
:
11110  
11111  
Poll PHY#1 thru PHY#31  
Poll all 32 PHY devices  
Setting PHYDEV[4:0] to poll more PHY devices than actually connected to  
the SCI-PHY/Any-PHY input port may result in loss of cell throughput due to  
longer than necessary polling cycles.  
NNI:  
The NNI bit selects whether the UNI or NNI cell header format is used when  
determining whether a cell is unassigned or reserved for the Physical Layer.  
When set to logic 1 (default), the NNI format is used. When set to logic 0, the  
UNI format is used, i.e. the 4 most significant bits of Byte 1 of the cell header  
are ignored.
