Hi Guys,
Can anybody offer a suggestion as to why the clkout signal is being superimposed onto 3.3v.

When I turn the pin back to an input (with mode set to inactive), it is being held at 3.3v, It should have no connections to 3v3 and I cannot see any shorts to 3v3 on the board?

Slightly puzzled!!!

Could suggest something if I would know which LPC we are talking about :confused:
Still LPC17xx ?

A piece of code could also be useful :)

Hi Zero,

This was my bad. Had the clkout connected to a tri state bus that was configured in the opposite direction.

oops

thanks for looking in tho!!!
