I have three question about SSI module of i.MX6

 1) In Section 61.8.7 Internal Frame and Clock Shutdown, it say that

SSI will stop driving the STFS/SRFS and STCK/SRCK signals after the current
frame ends.

"SSI will stop drivint" meen that each signal will go to high-impedance state like Figure 61-25.

Is it correct?


 2) If SSI_SCR.SSIEN = 0, every I/O or Output signal state will go to Reset state in Table 61-1.

     Is this correct?

  3) Section 61.2.1 Signals Overview in imx6dq reference manual, it say that 

The Synchronous Serial Interface (SSI) can be connected directly to the external pins or
through the Digital Audio Multiplexer (AUDMUX).

But section 61.8.3 SSI Architecture, it say that 

The Synchronous Serial Interface (SSI) is connected to chip pads through the Digital
Audio Mux (AUDMUX) block.

Which one is a correct answer?


Best regards,
