I am using a MSP430f2xxx series microcontroller... i wanted to know if there is any specific circuit diagram for the JTAG connection; i was browsing some websites where they have mentioned pull ups on the TDI and TDO pins of the 4-wire JTAG connections.. is there any specific requirement for MSP430 devices?
secondly, if the JTAG connector is not always hooked up to the JTAG pins, should the internal pull up or pull down resistors be enabled?
Can some1 plz help me?
You can find this information on the wiki:
That are only excerpts of hardware and user guides. Good starting point is here: http://www.ti.com/lit/ug/slau278h/slau278h.pdf

Found any horribly english mistakes? - Drop me a note as private conversation via my profile if you like ;-)
In reply to Jan:
I have checked that... it does not say anything about pull up or pull down resistors in any of the docs/... that's why i posted in forum
In reply to MSP430 Kors:
As far as I remember this is exactly what is used on my boards, there are no additional parts. With SBW the resistor and more the capacitor on the reset pin need some care as SBW is a very fast serial protocol and the capacitor should not be too large.
