I think, there is a confusion on pull-up, pull down resistors connected to JTAG interface of LPC177X.
In http://www.lpcware.com/content/faq/lpcxpresso/debug-design states that TCK pin should be connected to pull-down. In UM10470, it is connected to pull-up resistor.
Which one is correct?

This was asked recently (and answered). You didn't look very hard did you.

See here.
