Description
= 0X01
I2S communication I2S Philips standard, data launch at second BCK.
= 0X02
I2S communication MSB alignment standard, data launch at first BCK.
= 0x04
PCM Short standard, also known as DSP mode. The period of synchronization signal (WS) is 1 bck cycle.
= 0x0C
PCM Long standard. The period of synchronization signal (WS) is channel_bit*bck cycles.
__attribute__((deprecated)) = 0x01
I2S communication format I2S, correspond to `I2S_COMM_FORMAT_STAND_I2S`.
