If using USB UART mode the UART data will appear at the SPK_L and SPK_R pins if the
corresponding SpkLeftEn, SpkRightEn, or MicEn switches are enabled.
If using USB Audio the TxdEn and RxdEn bits should not be set when the SpkLeftEn, SpkRightEn, or
MicEn switches are enabled. The USB single-ended receivers described in
when either SpkLeftEn, SpkRightEn, or MicEn are set.
