|             Exported functions:
|
|             pei_create    - Create the Protocol Stack Entity
|             pei_init      - Initialize Protocol Stack Entity
|             pei_primitive - Process Primitive
|             pei_timeout   - Process Timeout
|             pei_exit      - Close resources and terminate
|             pei_run       - Process Primitive
|             pei_config    - Dynamic Configuration
|             pei_monitor   - Monitoring of physical Parameters
