9 / 60 page DS578F3 9 CS8416 SWITCHING CHARACTERISTICS - SERIAL AUDIO PORTS (Inputs: Logic 0 = 0 V, Logic 1 = VL; CL = 20 pF) Notes: 8. In Software Mode the active edges of OSCLK are programmable. 9. In Software Mode the polarity of OLRCK is programmable. 10. This delay is to prevent the previous OSCLK edge from being interpreted as the first one after OLRCK has changed. 11. This setup time ensures that this OSCLK edge is interpreted as the first one after OLRCK has changed.
