MCU Micro Controller Unit
BDM Background Debug Module
5 GENERAL REQUIREMENTS
The assumption made for the rest of this document is that a third party will supply the actual
hardware and partly FW used for this project. The exception is the use of the RF device described
later where the device supplied by ASSA ABLOY Hospitality shall be used.
It is also assumed the reader is familiar with the document “Orion Project Requirement
Specification” and “Orion Requirement Spec”.
MCU:s shall be of the Freescale HCS08 family (other types/brands can be used after approval).
5.1 User Interface
5.1.1 Introduction
The User Interface (UI) is the device where a local (in-room) user can check status of the energy
management system (e.g. set temperature, fan-speed) and control certain functions (e.g. alter set
temperature).
