I see. And about the efficiency-topic - since we're in the lite-C-forum here, I would like to use this with the standard-A7-commercial-compiler which comes with SED. Will it be able to handle it efficiently? Or should I rather use #define s? Does Lite-C itself even support bit-fields? (I suppose so, just to make sure)

On a web-page I read that "signed int flag1 :1;" will always have a value of either 0 or -1. However, the text didn't say anything about "unsigned int flag1 :1;"... May I run into problems here?
