Pontus, on the LPC2114 and all 64-pin LPC2000 devices that I know, you can pick either JTAG or ETM+JTAG so you got it right. On the LPC210x (48-pin devices)

I just read through the users manual for the LPC2114 and from what i can deduce the ETM output can be individually disabled simply by not tying a pull up
