Description:  
Header file for F243ILG1.C and F243ILG2.ASM
All these three files to gether implement a 
Special Function ADC Driver. 
This ADC Driver measures two channels on the timer underflow 
event. This is intended for implementing current measurement
for a inverter.

 Note 1 : It is necessary to call the init function to change the ADC 
            register settings, for the change in the channel setting for 
            either the channel A or B setting changes to take effect.
            The read function will not detect or act upon this change.
