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.

DESCRIPTION
When enabled an interrupt will be generated on the
alt_int of the RXCMD byte when the ID pin transitions
from non-floating to floating. The IdPullup bit in the
OTG Control register should be set.
