7. The active edges of OSCLK are programmable.
8. The polarity OLRCK is programmable.
9. No more than 128 SCLK per frame.
10. This delay is to prevent the previous OSCLK edge from being interpreted as the first one after OLRCK
11. This setup time ensures that this OSCLK edge is interpreted as the first one after OLRCK has changed.
