The USB-MODEVM Interface board is intended to be used in USB mode, where control of the installed
EVM is accomplished using the onboard USB controller device. Provision is made, however, for driving all
the data buses (I

the USB-MODEVM. Refer to Table 6 for details on the switch settings.
Additionally, SW3 on the USB-MODEVM (IOVDD SELECT) must be set up to 3.3V (SW3 position 1 on,
SW3 positions 2-8 off).
