    Apologies for the delay,

    In order to select your BOOT mode, the SOP[0:3] pins must be pulled either high or low depending on what mode you would like. By removing TXU0x, you would need another way to prevent your SOP pin from being pulled high or low continuously. I am not sure about the effects of pull up/down resistors on the SPI lines, but I have reached out to our experts to see what they know.

    Thank you,

    Susan
