S32K3xx - Use of PTE13 as GPIO. Last Mile regulator base control enable bit=0

I'm testing a board with S32K344-Q172 microcontroller.

I want to use PTE13 pin as GPIO141. 

I have disabled the last mile regulator base control. For that option I have tried these two ways:

Using both configuration options I still have fixed 3V on that pin (number 11)

Thank you

As a response to your questions: I am using an own design electronic board and yes, I am measuring PTE13 with a multimeter.

Following your suggestion, when reading PMC_CONFIG[LMBCTLEN] I have realised that it was not 0 so I wonder why the configuration done with the configuration tool was not working correctly (see screenshot on my previous post).

As an alternative, now I manually reset that bit in the register and now I successfuly measure 0 Volts on that pin.

Thank you.

Hi

Which board are you using? If it is EVB, please check the J31 jumper setting.

Did you measure the voltage on the PTE13 pin using a multimeter?

Did you confirm the value of PMC_CONFIG[LMBCTLEN]=0 when debugging?

Import Siul2_Port_Ip_Example_S32K344 example and select PTE13 as GPIO output in S32 Configuration Tool. Will the pin output low by calling Siul2_Dio_Ip_WritePin(GPIO141_PORT, GPIO141_PIN, 0U); ?

Sorry I didn't bring my multimeter and development board today, so it's not convenient for me to test it.

Best Regards,
Robin
