PHY Clock Select (PHY_CLK_SEL). This field is used to switch between
the internal and external MII clocks (RX_CLK and TX_CLK). This field is
encoded as follows:

โ€ข This field does not control multiplexing of the SMI port or other MII sig-
nals.
โ€ข There are restrictions on the use of this field. Please refer to Section
3.12, "MII Interface - External MII Switching," on page 34 for details.

Serial Management Interface Select (SMI_SEL). This bit is used to switch
the SMI port (MDIO and MDC) between the internal PHY and the external
MII port. When this bit is cleared to โ€˜0โ€™, the internal PHY is selected, and all
SMI transactions will be to the internal PHY. When this bit is set to โ€˜1โ€™, the
external MII port is selected, and all SMI transactions will be to the external
PHY. This bit functions independent of EXT_PHY_EN. When this bit is set,
the internal MDIO and MDC signals are driven low. When this bit is cleared,
the external MIDIO signal is tri-stated, and the MDC signal is driven low.
Note:
This bit does not control the multiplexing of other MII signals.

External PHY Detect (EXT_PHY_DET). This bit reflects the latched value
of the EXT_PHY_DET strap. The EXT_PHY_DET strap is used to indicate
the presence of an external PHY. This strap is latched from the value of the
external MDIO signal upon power-up or hard reset. If MDIO is pulled high a
โ€˜1โ€™ will be seen in this bit. If MDIO is pulled low a โ€˜0โ€™ will be seen in this bit.
The RXT_PHY_DET strap has no other effect on the internal logic. Its only
function is to give the system designer a mechanism to indicate the presence
of an external PHY to a software application.

External PHY Enable (EXT_PHY_EN). When set to a โ€˜1โ€™, this bit enables
the external MII port. When cleared, the internal PHY is enabled and the
external MII port is disabled.
Note:
โ€ข This signal does not control multiplexing of the SMI port or the TX_CLK
or RX_CLK signals.
โ€ข There are restrictions on the use of this bit. Please refer to Section 3.12,
"MII Interface - External MII Switching," on page 34 for details.

Soft Reset Timeout (SRST_TO). If a software reset is attempted when the
internal PHY is not in the operational state (RX_CLK and TX_CLK running), the reset
will not complete and the soft reset operation will timeout and this bit will be set to a
โ€˜1โ€™. The host processor must correct the problem and issue another soft reset.
