When an external clock (11.2896MHz, 12MHz , 12.288MHz, 13.5MHz, 24MHz or 27MHz) is input to MCKI pin, the
MCKO, BICK and FCK clocks are generated by an internal PLL circuit. The MCKO output frequency is fixed to 256fs,
the output is enabled by MCKO bit. The BICK is selected among 16fs, 32fs or 64fs, by BCKO1-0 bits. (See Table 9)
When BICK output frequency is 16fs, the audio interface format supports only Mode 0 (DSP Mode).
