he following example will generate I2S interface format from the W681308 PCM interface.
S for 48KHz Sampling Rate(SR) with 16bits LPCM :
70 = 85
70 [2:0]
70 [4:3]
70 [7]

I2S Register Setting Example
:
(Enable Gain Stag
(Enable PCM)
(Mute CODEC D/A OUT)
e, Link PCM_USB)
101 = BCLK Rate Select. SR x 32 bits = 48K x 32 = 1.536MHz ( L,
R channels are 16 bits format)
00 = FST Location, Frame Sync is occurred before the MSB of the
PCM data.
1 = Enable PCM Interface
F0 = For long frame
40 = PCM bit clock inverse enable
