5.2.4 Prototyping Board Functions
The functions described in this section are for use with the Prototyping Board features.
The source code is in the Dynamic C
LIB\RCM4xxx\RCM40xx.LIB library if you need
to modify it for your own board design.
NOTE: The analog input function calls are supported only by the RCM4000 model since
the RCM4010 does not have an A/D converter.
Other generic functions applicable to all devices based on Rabbit microprocessors are
described in the Dynamic C Function Reference Manual.
