Q: Please help answer questions: i.MX280 the GPIO level is 1.8V or 3.3V? GPIO can be configured

individually or in any of these two levels? [translated by Google]

Hi alyssa

please refer to sect.9.2.2.2 Pin Voltage Selection MCIMX28RM  :

Each GPIO (non-EMI) pin can be programmed to operate at either 1.8 V or 3.3 V by setting

the bit corresponding to that pin in one of the HW_PINCTRL_DRIVEx registers. The EMI

pins are capable of running at 1.5/1.8 V depending on the EMI_VDDIO voltage.

Best regards

igor
