Switching off pin68 (SD_PWR) for reduced power consumption


#1

I would like to know if there is a way to tell the EMX module to switch ON or OFF pin 68 (SD_PWR) that brings 3.3V to the SD Card?

My ultimate goal is to offload as much power consumption from the EMX Dev kit board when a power fail event is detected at the power supply.

You can only do it by directly accessing the processor registers.

We do not support this directly so you need the NXP datasheet fro more details.
