According to the datasheet:
Page0 / Register8: Audio Serial Data interface Control Register A BIT 7: Bit Clock Directional Control 0: Bit clock is an input (slave mode) 1: Bit clock is an output (master mode)
BIT 6: Word Clock Directional Control 0: Word clock is an input (slave mode) 1: Word clock is an output (master mode)
Current code sets BIT_CLK_MASTER and WORD_CLK_MASTER bits for master mode, but does not clear these bits for slave mode.
