3.0 I2S INPUT INTERFACE CONFIGURATION
In order to configure the I2S input interface the Configuration Register B (CRB) can be used. Using the 3
I2SI_Align_x bits one of 6 configuration mode can be selected. Following is a table describing each one of them.
By default standard I2S input interface slave is provided (mode 1 in bits 0,1,2 of register CRB, I
I2SI_LRCK_Pol = 0 with some register)
