Section 34 Serial Sound Interface (SSI)
(7)
There are several more configuration bits in non-compressed mode which will now be
demonstrated. These bits are NOT mutually exclusive, however some configurations will probably
not be useful for any other device.
They are demonstrated by referring to the following basic sample format shown in figure 34.9.
