Connect the boot mode pins to a 4.7 kW or lower pull-up resister to VCCO_PSIO[3] or pull-down to ground depending on the desired setting.

If multiple switchable boot modes are desired, connect one pull-up/down resistor to the mode pin and place a jumper on the other side of the resistor to select between pull-up or pull-down.

An easily switchable boot mode configuration is recommended for debug ease-of-use.
