†A crystal oscillator is connected to XTL_IN.
‡MCLK_IN tied low when input to XTL_IN is provided; XTL_IN tied low when MCLK_IN_IN is provided.
§External MCLK_IN connected to MCLK_IN_IN input
¶SCLK and LRCLK are outputs when M_S=1, and inputs when M_S=0.
#MCLK_OUT is driven low when M_S=0.
|| Quad-speed mode is detected automatically.
kSCLK can be 48 or 64 times Fs
