Management Data Clock: When  
SMI_SEL = 1, this pin is the MII  
management data clock. When  
SMI_SEL=0, this pin is driven low.  
See Note 2.2.  
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.
