PLL Master Mode (PMPLL bit = “1”, M/S bit = “1”)
When an external clock (11.2896MHz, 12MHz, 12.288MHz, 13MHz, 13.5MHz, 19.2MHz, 24MHz, 26MHz or 27MHz)
is input to MCKI pin, the MCKO, BCLK and LRCK clocks are generated by an internal PLL circuit. The MCKO output
frequency is selected by PS1-0 bits (see Table 9) and the output is enabled by MCKO bit. The BCLK output frequency is
selected among 32fs or 64fs, by BCKO1-0 bits (see Table 10).
