   1) EPF interface: Interface CPU with PCI BUS, and send audio signals to CPU and HD2 by
                    PER communication

   2) ADC à HD2 CHIP I2S signal : AUDIO_IN_SCLK, AUDIO_IN_DATA_H,AUDIO_IN_LRCLK.

   3) HD2 à I2S signal to MSP4440 : HA_DAC_SCK, HA_DAC_LRCK, HA_DAC_LRCH

   4) By measuring MNT_OUT of AUDIO Test, the problem can be found whether it’s the front
      or back of MSP_4440.

   5) The signal related to recording is controlled by SUB_MSP.
