AM67: Applying power to un-sequenced and un-powered GPIO on the AM67

Part Number: AM67

Hello TI team,
My colleague and I want to know what would happen if we were to apply power to an unpowered GPIO prior to sequencing. Could you possibly confirm if this would cause any issues?

    Nicolas,

    The datasheet lists all pins that are fail-safe and those that aren't. 

    MCU_I2C0_SCL, MCU_I2C0_SDA, WKUP_I2C0_SCL, WKUP_I2C0_SDA,
    EXTINTn, VMON_1P8_SOC, VMON_3P3_SOC, and MCU_PORz are the only fail-safe IO terminals. All others are not fail safe and no power should be applied when the terminals are not powered.

    regards,

    Michael
