Hi,  what is the default status of the S32K144 MCU I/O port , at the  power-on moment ?

(High, low, or high resistance)?

Should I set initial value field from Low to High ? 

Other options in below picture, what is the recommended setting, when I control the led on and off ?  Thanks.

I don't  want any I/O port work, at the  power-on moment.

I  use  Processor  Expert  in  S32DS For Arm 2.2 Version,  with  S32K144-100EVB board.

Only control  PTD0 on,  PTD15 and PTD16 both Off.
