1. I found that DCF records can  trim the internal capacitor values, so I want to know how much the default capacitor value is and how to trim it. If I set UTEST Miscellaneous[5:1]  (XOSC LOAD CAP SEL) as 1 ,2 or 3 etc., how much the capacitor value change.

 

2. I found that there is no UTEST Miscellaneous value in the DCF of MPC5777M EVB, so I think the external OSC is disabled. But the example code works well on it. So I want know if I should configure XOSC DCF records. What effect If I don't configure DCF records.
