5.2.3 Digital I/O
The RCM3750 was designed to interface with other systems, and so there are no drivers
written specifically for the I/O. The general Dynamic C read and write functions allow
you to customize the parallel I/O to meet your specific needs. For example, use
to set all the Port E bits as inputs, or use
to set all the Port E bits as outputs.
When using the auxiliary I/O bus on the Rabbit 3000 chip, add the line
to the beginning of any programs using the auxiliary I/O bus.
The sample programs in the Dynamic C
folders provide further examples.
