Data Sheet
ATM side and PHY side UTOPIA Interfaces can be configured independently in either
the 8-bit or the 16-bit mode.
Note: Octet UDF2 is internally used for BIP8 supervision.

5.1.1
To support multi-PHY configurations with or without use of the UTOPIA PHY address,
the Infineon ATM switching chip set supports the Appendix 1 option of the UTOPIA Level
2 Standard [2]. It allows the simultaneous polling of up to four groups of PHYs by using
four CLAVx/ENBx signal pairs (x=0..3).
