1. Master mode timing specifications are characterized, not production tested.
2. Master mode is defined as the CS4953xx driving both DAO_SCLK, DAO_LRCLK. When MCLK is an input, it is
3. This timing parameter is defined from the non-active edge of DAO_SCLK. The active edge of DAO_SCLK is the
4. Slave mode is defined as DAO_SCLK, DAO_LRCLK driven by an external source.
