In a point-to-multipoint or in a multimaster configuration the HSCC can be used as a central station (master) or a peripheral station. As a peripheral station the HSCC can initiate the transmission of data. An internal function block provides for collision avoidance, which may occur if several stations start the transmitting simultaneously. Furthermore, in a.
