Timestamp of received CAN message (unit: micro second).
Reserved and no used for transmitted CAN message
All the parameters are in 16-bit and 32-bit (2 and 4 bytes) format. The data for 16-bit (2 bytes)
size is in high-byte first format. For example: 0x0A0B
0x0A, 0x0B. And the data for 32-bit (4
bytes) size is in high-byte first. For example: 0x0A0B0C0D
0x0A, 0x0B, 0x0C, 0x0D.
NOTE:
[1]:
This ESI bit is valid when receiving a CAN FD frame
。
[2]:
When EVE=1 and XTD=1, the CAN Message ID parameter will be equal to 0xEEEEEEE and
CAN Data Length Code will be equal to 8. Then the content of CAN Data will be used for the
CAN status (data 0-3) and error counter (data 4-7) of CAN bus (Refer to
for detail description of the CAN status and error counter).
[3]:
CAN FD frame bit rate switchable. This BRS bit is valid when FDF=1.
[4]:
When FDF=1, the RTR bit cannot set to 1.
[5]:
The size of CAN Data is fixed to 64 bytes. When the “CAN Message format” is a CAN frame,
this field will use up to 8 bytes of data. When it is a CAN FD frame, this field will use up to 64
bytes of data.
