    Hi Sunny,

    The bootmode pins are latched when the part is released from reset. During this time, the GPIO function is disabled so that the pins are not driven. Typically the bootmode is set by including a pull up or pull down resistor on the bootmode pins. If you are using the GPIO pins as an input driven by some other source, the output of that source must be disabled so that the bootmode setting can be correctly latched. 

    Regards,
