5.2.2 Analog Inputs
NOTE: The function calls for the A/D converter in this section will work only with the
RCM3700 Prototyping Board.
Use this function to configure the ADS7870 A/D converter. This function will address the ADS7870 in
Register Mode only, and will return error if you try the Direct Mode. This appendix provides additional
addressing and command information.
