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
11. This setup time ensures that this OSCLK edge is interpreted as the first one after OLRCK has changed.
