Use the members of this class to add or access sporadic frames.

Sporadic frames attempt to provide dynamic behavior to LIN. Sporadic frames always carry signals (data), and their IDs are 0–59 (0x3B). Only the slave task associated with the master node can send sporadic frames. The header of a sporadic frame is sent in its frame slot only when the master task knows that a data value (signal) within the frame has been updated. If multiple unconditional frames associated with a sporadic slot have updated data, the master transmits only the highest priority frame, which the order that the frames appear in the sporadic frame list determines.
