Software Reset : 0
Description :
If OUTPUT_CONF == 1, configure the divider to generate the bit clock of the I
called BCK0, from PCMCK. according the following relation : BCKO = PCMCK / 2 *
(PCM_DIV+1)
PCM_CONF :
Address : 0x68 (104)
Type : RW - DEC
Software Reset : 0
Description :
If OUTPUT_CONF == 1, configure the I

0 : 16 bits mode (16 slots transmitted).
1 : 18 bits mode (18 slots transmitted).
2 : 20 bits mode (20 slots transmitted).
3 : 24 bits mode (24 slots transmitted).
Polarity of BCKO :
0 : data are sent on the falling edge & stable on the rising).
1 : (data are sent on the rising edge & stable on the falling).
0 : I2S format is selected
1 : other format is selected
Polarity of LRCKO :
0 : low->right, high->left).
1 : low->left, high->right so compliant to I2S format ).
0 : data are in the last BCKO cycles of LRCKO (right aligned data).
1 : data are in the first BCKO cycles of LRCKO (left aligned data).
0 : the transmission is LS bit first.
1 : the transmission is MS bit first.
