i am using DS33Z44 for IP to E1/E3 project and for Ethernet interface i a
using 2 Phys(DP83849IF) each contains two internal PHY's(both internal PHY
have unique LSB of PHY address).now the thing i don't understand is eac
Phy has to configured with unique PHY address normally. but for the case o
DS33Z44 which says that MDIO/MDC is only accessible by first MAC block o
DS33Z44,and application note says MDIO lines of all phys and DS33Z44 nee
to be short and external address should be same too . in that case i ca
only configure one Phy-Address for all PHYs.so how can DS33Z44 identif
which PHY is one,two three and four. can someone help me understand tha
architecture.
