Description:  
Header file for F07ILVD1.C and F07ILVD2.ASM
All these three files to gether implement a 
Special Function ADC Driver. 
This ADC Driver measures three channels on the timer underflow 
event. This is intended for implementing two current measurement
and DC-bus voltage measurement for a inverter.
