    Hi Hsiao,

    The TLK10232 will respond if the 4MSB's of the port add field on MDIO protocol (PA[4:1]) matches PRTAD[4:1].
    PA[1:0] = 1'b0 Channel A will respond
    PA[1:0] = 1'b1 Channel B will respond
    This is according to the Clause 45 (ST=0) and Clase 22 (ST=1) to determine the device port address. Please take a look into the section 7.6 MDIO Management Interface of TLK10232 datasheet.
