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.
