Default Configuration and Connections
2.2.1
USB-MODEVM
provides a list of the SW2 settings on the USB-MODEVM. For use with the TLV320AIC3253EVM,
SW-2 positions 1, 3, 4, 5, 6, and 7 must be set to ON, whereas SW-2.2 and SW-2.8 must be set to OFF. If
the TLV320AIC3253EVM is to be used with an external audio interface, SW2.4 and SW2.5 also need to
be set to OFF and such interface must be connected as explained in
