About I/O default status

I have questions about  ADUCM3029 IO ports.

 

#1, What is the default condition for I/O pin? Is it input? Is it output? Is it Hi-Z?

I want to know the condition before setting Input Input/Output Enable register.

It looks like Hi-Z according to the fig,

#2, Which register is a bigger priority, GPIO_IEN or GPIO_OEN?

For example setting both GPIO_IEN and OEN as '1'.

 

Best regards,

Tarzan
