The CLK mode 2S is used when the BITCLK_I is used instead of XTI. When selecting this mode, set SMODE=”L”.
The clock supplied on the BITCLK_I pin is directly frequency- multiplied by the PLL and a master clock is
generated. When the system is using this mode only, it is recommended to connect the XTI pin to DVSS.
Input on BITCLK_I pin a divided-by-64 clock of the LRCLK_I ( 64fs ). (BITCLK_I must be in synchronized with
LRCLK_I. )
