When an external clock (11.2896MHz, 12MHz, 12.288MHz, 13.5MHz, 24MHz, 25MHz 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
32fs or 64fs, by BCKO bit
MS0991-E-00
PLL Master Mode (PMPLL bit = “1”, M/S bit = “1”)
(Table
