Carkit Control Registers
The following registers are used to set-up and enable the USB UART and USB Audio functions.
Carkit Control
Address = 19-1Bh (read), 19h (write), 1Ah (set), 1Bh (clear)
This register is used to program the USB3320 into and out of the Carkit Mode. When entering the
UART mode the Link must first set the desired TxdEn and the RxdEn bits and then transition to Carkit
Mode by setting the CarkitMode bit in the
DATA[1] pin is held to a logic high.
Note: If SpkRightEn or MicEn are asserted the DP pin will be connected to SPK_R. To disconnect
the DP pin from the SPK_R pin both SpkrRightEn and MicEn must be set to de-asserted.
