I am currently designing a board with LPC4330. I have observed that some of the pins have as function #0 (default function) output states. The pins are the followings (on my TQFP144 package):

- P4_7 -> LCD_DCLK
- PF_4 -> SSP1_CLK
- CLK0 -> EMC_CLK0
- CLK2 -> EMC_CLK3

My questions are:

1) Are these really outputs after reset?
2) What are the waveforms or logic states after reset?
3) During reset they are Hiz or outputs?

Thanks for help.
