With respect to command length, there are two types of services from the host controller:
• Single−byte commands: the control byte is the only data sent from the host controller to NCN5130.
• Multiple−byte commands: the following data byte(s) need to be handled according to the already received control byte.
With respect to command purpose there are two types of services from the host controller:
• Internal command: does not initiate any communication on the KNX bus.
• KNX transmit data command: initiates KNX communication
