5.2.7 Prototyping Board Function Calls

The functions described in this section are for use with the Prototyping Board features.
The source code is in the Dynamic C
to modify it for your own board design.
NOTE: The analog input function calls are supported only by the RCM4200 model since
the RCM4210 does not have an A/D converter.
The sample programs in the Dynamic C
the function calls.
Other generic functions applicable to all devices based on Rabbit microprocessors are
described in the Dynamic C Function Reference Manual.
