Notes:
*1: Refer to the I2S register description chapter in the
for different combinations of clock polarity (CPOL), sampling point
position (SMPL), polarity/pulse_width/frame_sync phase of WS (FSPL, FSLN, FSPH). Actual waveforms and relevant clock
edges will change accordingly; the delay values listed in the previous table will remain the same.
