Configure allocated pins as GPIO - preferred way?

I am working with a KL25 MCU, configured by Processor Expert under KDS 3.0.0. Some pins are muxed to SPI peripherals, among others.


When switching to low power mode, I need to set the output states of these pins, or switch them to act as inputs, to avoid drawing unnecessary current through external pull resistors, or asserting push-pull outputs into ICs that are externally powered-off.


Is there a preferred method in Processor Expert to allow a pin's configuration to swap between a peripehal and a pre-defined GPIO configuration at runtime?
