Workflow

1.
Create an FREQM device instance struct, which will be associated with a FREQM peripheral hardware instance.
```
static struct freqm_module freqm_instance;
```
Note: Device instance structures shall never go out of scope when in use.
2.
Create a new function configure_freqm(), which will be used to configure the overall FREQM peripheral.
```
void configure_freqm(void)
```
3.
Create an FREQM peripheral configuration structure that will be filled out to set the module configuration.
```
struct freqm_config config_freqm;
```
4.
Fill the FREQM peripheral configuration structure with the default module configuration values.
```
freqm_get_config_defaults(&config_freqm);
```
5.
Initialize the FREQM peripheral and associate it with the software instance structure that was defined previously.
```
freqm_init(&freqm_instance, FREQM, &config_freqm);
```
6.
Enable the now initialized FREQM peripheral.
```
freqm_enable(&freqm_instance);
```
