SAI_CLK[3:0] – Selects the serial audio input master clock-to-ILRCK ratio when the serial audio input port
is set to master mode (SIMS = 1 as shown in “Serial Audio Input Data Format (0Bh)” on page 53). Note: if
a serial audio output is sourced directly by the serial audio input port, SAI_CLK[3:0] determine the
MCLK/LRCK ratio for both serial ports if they are set to master mode.
0000 - ILRCK = MCLK/64
