W17 2-pin Open Selects onboard EEPROM as TAS1020B Firmware Source.(Not Used). Note that for this EVM the Firmware SourceEEPROM is on the USB-MODEVM.
W18 2-pin Open Selects SWOUTP to J-18. Caution: Make sure that the Class-D Output is Disabled before Installing W18.
W19 2-pin Open Selects SWOUTM to J-18. Caution: Make sure that the Class-D Output is Disabled before Installing W19.

The TLV320AIC3007 can be powered independently when being used in stand-alone operation or by theUSB-MODEVM when it is plugged onto the motherboard.
When used as a stand-alone, power is applied to J15 directly; be sure to reference the supplies to theappropriate grounds on that connector.
CAUTION
Before applying power to the EVM, you must verify that all power supplies arewithin the safe operating limits as indicated in the TLV320AIC3007 data sheet .
J15 provides connection to the common power bus for the TLV320AIC3007EVM. Power is supplied on thepins listed in Table A-3 .
The TLV320AIC3007EVM-K motherboard (the USB-MODEVM Interface board) supplies power to J15 ofthe TLV320AIC3007EVM. Power for the motherboard is supplied either through its USB connection or viaterminal blocks on that board.
The USB-MODEVM Interface board can be powered from several different sources:
•USB
•6-Vdc to 10-Vdc ac/dc external wall supply (not included)
