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. However, provision is made for driving all
the data buses (I

C, SPI™, and I
2
S/AC97) externally. The source of these signals is controlled by SW2 on
the USB-MODEVM.
Before installing the TSC2007EVM board on top of the USB-MODEVM board, check SW2-1, SW2-2, and
SW2-3 on the USB-MODEVM board to ensure that at least one of these three is OFF
Ensure that the TSC2007EVM is installed on the USB-MODEVM interface board. The TSC2007EVM
should be installed in the topmost position, using J11, J12, and J13 on the USB-MODEVM.
