S OUTPUT INTERFACE CONFIGURATION
To configure the I
2
S output interface the
Configuration Register B (CRB)
is used. Using the three
I2SO_Align_x bits one of the seven configuration modes can be selected. Table 3 describes each of
them.

S output interface master is provided (mode 1 in bits D8, D9 and D10 of register
CRB, I2SO_BICK_Pol = 1 and I2SO_LRCK_Pol = 0 in the same register).
