// NB: when adding new values, you have to also increase EV_COUNT_EMC

// hours trying to work out why your functions do not get called, as
// I did :) (Tomas)
//
// Foddex:  the values for the various contexts were bad. The EV_EMC_ToNumber
//          define is used to make an index out of the context bits. It is
//          used assuming that it will never yield a value larger than or
//          equal to EV_COUNT_EMC. However, the original values were defined
//          in such a way that it often was bigger dan EV_COUNT_EMC. E.g.
//          0xe0000000 >> 27 = 28, which is bigger than EV_COUNT_EMC. I therefor
//          rearranged the values. I just hope noone ever was so stupid to use
//          hardcoded values...
