This demo (apb3Demo directory) shows how to use an APB3 slave peripheral where APB3 slave is attached to a pseudorandom number generator. When user run the application, the Sapphire SoC programs the APB3 slave to stop generating a new random number and reads the last random number generated. The test passes if the returned data is a non-zero value.

Note: The structure of apb3_instance_t (app/apb3_slave.h) is based on the Demo only! User might need to modify the structure of apb3_instance_t based on custom APB3 slave module.

Newlib

By default, newlib-nano is used for this demo.
