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.
