S32K344 platform，PE0 Used to Feed an external watchdog，So I used the LLD Gpraphical Configuration to Configue the IO to gpio with Direction setted Output, But when the System goes to DeepSleep mode,the

watchdog needed to stop,So I need to Confige the IO to HighZ State. I need the IO Configuration to switch between Output and HighZ freely. But i cant find the Interface Function in the Code System supplied.

Please download the S32K3_low_power_management.zip from S32K3 Low Power Management AN and demos.

Read the chapter 7. Pad keeping in Standby mode of S32K3xx Low Power Management.pdf.

Hope it helps.
