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 (I2C, PCM/SMARTDM™) externally. The source of these signals is controlled by SW2 on 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).
