PHYDEV[4:0]:
The PHYDEV[4:0] bits are used to define the polling range of the SCI-
PHY/Any-PHY output port when configured as a bus master (OMASTER 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 output port may result in loss of cell throughput due to
longer than necessary polling cycles
