4.7 MDC/MDIO Interface for MIIM Registers mode and SMI mode   

From MDC/MDIO interface to the KSZ8895ML, use a USB to MDC/MDIO converter that allows 
accessing all of PHY related registers by MIIM mode and all of the KSZ8895ML registers by SMI 
mode. The user can easily access the MDC/MDIO interface using a computer connected to the 
evaluation board’s USB port interface. Micrel provides Windows based programs for the user to 
evaluate for both MIIM and SMI. For the MIIM software to be used all of PHY related registers, 
please use the software tool in the folder of MDC_MDIO MIIM of the software directory. For the 
SMI software to be used all of registers, please use the software tool in the folder of MDC_MDIO 
SMI of the software directory. 

To prepare the KSZ8895ML evaluation board for MDC/MDIO configuration, please follow 
these steps:  
1.  Copy the Micrel provided software on your computer.  
2.  Set JP2, JP3 and JP4 as specified in Table 8 for MDC/MDIO configuration.

8.

 

Connect the computer’s USB port to the KSZ8895ML board with a USB port cable.  

9.

 

There are two ways to power up the evaluation board: 

a). Connect the 5 VDC power supply to the KSZ8895ML when JP44 pin1-2 is closed. 

       b). 5 VDC power source from the USB port when JP44 pin 2-3 is closed. 
10.

 

The KSZ8895ML will power up initial default configuration with the start switch in register 1 
bit 0 = ‘0’ which means the switch is “off”. You can set the bit 0 =’1’ to start switch in SMI 
mode. When JP5 and JP4 are open, the switch will be started automatically when power up.  

11.

 

Open the Windows and navigate to the directory where the Window MDC/MDIO files are 
stored. Click its icon to invoke the software.  

12.

 

Program the desired settings using the Micrel MDC/MDIO software.  See the software 
operation description section for details.
