    Thank you for pointing this out.  I believe the error in the document is the reference to the MSP432E401Y device which is not the same as the MSP432P401R device.  

    I would not recommend using a pull-down unless you had sufficient concern about noise and the internal pull-down not being strong enough.  This is exemplified in the MSP-EXP432P401R launchpad which does not have any external resistors pulling down (or up) on the jtag lines.

    Hope that is more clear.

    Regards,

    Chris
