Abstract

A communication device includes a first processing unit that sends a first command to start an activation processing. The communication device also includes a second processing unit that receives the first command from the first processing unit. In addition, the communication device includes an interface between the first processing unit and the second processing unit. The first processing unit activates the interface at a predetermined interface level from among a plurality of interface levels. The second processing unit starts an application in accordance with the activated interface level. The first processing unit and the second processing unit exchange data by the activated application. The first processing unit and the second processing unit perform a deactivation processing of the activated interface.
