Silicon Labs F530 and C2 Flash Programming AN127

This should be the last word on this. The VDDMON change posted earlier is the one change that must be made to the code in AN127. The FPI initialisation sequence is possibly a red herring. I tried the sequence of 0x02, 0x01 from AN127, and it works just fine. Intrigued as to why two different sequences appear to work, I tried 0x02 on its own (doesn't work) and 0x01 (appears to work). The tests were separated by warm resets (RST line low), so there's possibly some chance the initialisation was surviving the reset, but now that this hurdle to progress has gone, I've lost all interest!
