Sterling-LWB PCM/I2S configuration.

Question: What are the PCM/I2S configurations of the Sterling-LWB?  Answer: The PCM/I2S (BT_I2S_DI & BT_PCM_IN) inputs are shared on the module depending on the BT Audio configuration. That configuration is set by using a VS HCI command in Linux (write_I2SPCM_interface_param. The HCI UART is required, then either I2S or PCM, but not both.    Pin Description Module Pin # SIP Pin #   BT_PCM_SYNC 2 144   BT_PCM_IN 3 146   BT_PCM_OUT 4 145   BT_PCM_CLK 38 55   BT_I2S_CLK 35 105   BT_I2S_DO 36 110   BT_I2S_WS 37 109
