9.1.1.3 Workflow

  1. Create a TRNG device instance struct, which will be associated with a TRNG peripheral hardware instance. 
    static struct trng_module trng_instance;
    Note: Device instance structures shall never go out of scope when in use.
  2. Create a new function configure_trng(), which will be used to configure the overall TRNG peripheral. 
    void configure_trng(void)
  3. Create a TRNG peripheral configuration structure that will be filled out to set the module configuration. 
    struct trng_config config_trng;
  4. Fill the TRNG peripheral configuration structure with the default module configuration values. 
    trng_get_config_defaults(&config_trng);
  5. Initialize the TRNG peripheral and associate it with the software instance structure that was defined previously. 
    trng_init(&trng_instance, TRNG, &config_trng);
  6. Enable the now initialized TRNG peripheral. 
    trng_enable(&trng_instance);
