Mapping of the N_PDU fields - from ISO15765-2
Addressing formats
The exchange of network layer data is supported by three addressing formats: normal, extended and mixed addressing. Each addressing format requires a different number of CAN frame data bytes to encapsulate the addressing information associated with the data to be exchanged. Consequently, the number of data bytes transported within a single CAN frame depends on the type of addressing format chosen.
The following (7.3.2 to 7.3.5) specifies the mapping mechanisms for each addressing format, based on the data link layer services and service parameters defined in ISO 11898-1.

解析.DBC文件, 读懂CAN通信矩阵，实现车内信号仿真
通常我们拿到某个ECU的通信矩阵数据库文件，.dbc后缀名的文件。 直接使用CANdb++ Editor打开，可以很直观的读懂信号矩阵的信息。
