Kinetis 1.8 volts I/O

Hello.

 

I'm new to Kinetis and I need to communicate to a GSM module that runs at 1.8 volts.

 

How am I able to configure the FRDM-KL05Z board to use some I/Os at that voltage level?

 

I see that there is a reference to that supply voltage at the P5-9V_VIN pin but I'm not sure how to set it.

 

Could anybody help me with that?

 

I'd really appreciate it.

 

Many thanks!
