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);
```
