I am learning to how to configure the MPC5775K .I want to use the SD_ADC. but there are some problems：
1.how to trim VREF and VREG's if default values are not sufficient.
2.what is the "Magic Carpet module"?How to turn on SDPLL using the Magic Carpet module?
3.When I trim the resistor and capacitor,Do I need to write ADCTRIM[RESCODE] and ADCTRIM[CAPCODE] to other register?Or Send any read command?
