[I210-IT] schematic design - JTAG_CLK pullup or pulldown ?

Hello Support Team,

 

    I am desgining a product with I210-IT.  I wonder to know how to treat the JTAG_CLK pin if JTAG interface is not used.  in I210 datasheet ver 3.7 Table 14-1, it is said Signal should be connected to ground through a 3.3 KΩ pull-down resistor, but in checklist ver 2.7, it is said Pins JTAG_TDI(29), JTAG_CLK(19) and JTAG_TMS(18) should be pulled high with 3.3K Ω resistor value.  

    I am confused. Which is correct if JTAG interface not used ?

    Can you help me ?
