means to delete the currently selected mapping rule.
means to modify the currently selected mapping rule.
means to clear all mapping rules in the current table.
means to move the currently selected mapping rule up and down. The
smaller the sequence number of the mapping rule, the higher the priority. That is, once a
frame satisfies one mapping rule, it will not continue to check other mapping rules.
4.3.6 Frame Mapping Example
In the example, two CAN0 frame mappings are set, as shown in Figure 4.22. The first
is that the CAN standard frame is mapped to the CANFD extended frame, and the data is
mapped; the second is that the CAN standard frame is mapped to the CAN standard
frame, and the data is not mapped.

Use data mapping
The configuration is shown in Figure 4.23. Map the CAN standard frame with ID 0x02,
data 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 to ID 0x333, data 0x11, 0x22, 0x33,
0x44, 0x55, 0x66, 0x77, 0x88, CANFD extended frame of 0x99, 0x10, 0x11, 0x12. Figure
4.24 shows example results.
