Management Data Clock: When

SMI_SEL = 1, this pin is the MII

management data clock. When

SMI_SEL=0, this pin is driven low.

Note:

See Section 5.3.9,

"HW_CFG—Hardware

Configuration Register" for

more information on

SMI_SEL.

Note 2.2 The external SMI port is selected when SMI_SEL = 1. When SMI_SEL = 0, MDIO is tri-

stated and MDC is driven low.
