USB334x
In USB audio mode, a switch connects the DP pin to the SPK_R pin, and another switch connects he DM pin to the
SPK_L pin. These switches are shown in the lower left-hand corner of .The USB334x can be configured to enter USB
audio mode as described in Section 6.7.2, "USB Audio Mode (USB3341 and USB3346)," on page 61. In addition, these
switches are on when the RESETB pin of the USB334x is asserted. The USB audio mode enables audio signaling from
a single USB port of connection, and the switches may also be used to connect Full Speed USB from another trans-
ceiver to the USB connector.
