26.8.2.2.2 Workflow

  1. Make the application loop infinitely. 
    while (true) {
  2. Start an asynchronous TRNG read job, to store random data into the global buffer and generate a callback when complete. 
    trng_read_buffer_job(&trng_instance, random_buffer, 5);
  3. Wait until the asynchronous read job is complete. 
    while (!trng_read_done) {
}
trng_read_done = false;
  4. Toggle the board LED to indicate specific size of random data were read. 
    port_pin_toggle_output_level(LED_0_PIN);
/* Add a short delay to see LED toggle */
volatile uint32_t delay = 50000;
while(delay--) {
}
