When an external clock (11.2896MHz, 12MHz, 13MHz, 14.4MHz, 15.36MHz, 19.2MHz, 19.68MHz,19.8MHz, 26MHz
or 27MHz) is input to the MCKI pin, the MCKO, BICK and LRCK clocks are generated by an internal PLL circuit. The
MCKO output frequency is selected by PS1-0 bits
frequency is selected between 32fs or 64fs, by BF bit
MS0684-E-02
PLL Master Mode (PMPLL bit = “1”, M/S bit = “1”)
