    摘要: A microcontroller has a random access memory, and a Controller Area Network (CAN) controller with a control unit receiving an assembled CAN message. The control unit generates a buffer descriptor table entry using the assembled CAN message and stores the buffer descriptor table entry in the random access memory, and the buffer descriptor table entry has at least a message identifier and load data from the CAN message and information of a following buffer descriptor table entry.

    摘要: A controller area network (CAN) controller unit has a message assembly buffer receiving a serial bitstream, a buffer memory coupled in parallel with said message assembly buffer, a CAN control unit coupled with the message assembly and the buffer memory, and at least one control register. The at least one control register can be programmed to cause the CAN control unit to store a message received in the message assembly register in at least a first and second mode, wherein in the first mode, control information and data payload of the received CAN message are stored in the buffer memory and in the second mode only the data payload of the CAN message is stored in the buffer memory.
