Notes:
1. The value "00000" is a broadcast PHY address and should not be used to avoid contention between the
internal HARD_TEMAC PHY and the external PHY(s).The value "00000" is a broadcast PHY address and
should not be used to avoid contention between the internal HARD_TEMAC PHY and the external PHY(s).
2.
Allowable Parameter Combinations
Each HARD_TEMAC includes two EMACs. If only one EMAC is used it must be EMAC 0 and
C_EMAC1_PRESENT should be set to ’0’.
Detailed Parameter Descriptions
C_PHY_TYPE
The PHY Type parameter selects which PHY interface will be used by EMAC 0 (and EMAC 1 if
present).
C_EMAC1_PRESENT
This parameter is used to indicate if both EMACs in the HARD_TEMAC are used or not used. If this
parameter is set to ’1’ then both EMACs will be used otherwise only EMAC 0 will be used.
