Mode Selection Definition: This bit lets the receiver know where the device is located in a system for the

purpose of centering the AEQ point. The SNx5DP149 is targeting the source application, so the default value is

0, which will center the EQ at 6.5 to 7.5-dB , see Table 9. If the SNx5DP149 is in a dock or sink application, the

value should be changed to a value of 1, which will center the EQ at 12 to 13-dB .
