CC2640R2F: under serial bootloader mode, what's the DIO default status

Hi team,

my customer would like to understand what's the DIO default status when CC2640R2 enter serial bootloader mode ?

I check the TRM, swcu117i. By default, the pins are at tri-state mode at power on or reset.

So, when CC2640R2 enter serial bootloader mode, except for serial interface, the pins are also at tri-state mode, right ?

Thank you.
