2. Converting serial frames to CANFD messages
Suppose the configuration CAN type is CANFD, the frame information is "standard
frame", the baud rate acceleration is enabled, the frame ID1 and ID0 are "0x01, 0x23"
respectively, the serial frame data is 0x01-0x46, a total of 70 data, the conversion format
is listed in Table 4.7. The frame ID of the CAN message is 0x0123 (configured by the user),
the frame information is a standard frame (configured by the user), the EDL bit
corresponding to the CANFD message is 1, the BRS bit corresponding to baud rate
acceleration is 1, and the data in the serial frame part will be converted into CANFD
message without any modification. Because there are 70 bytes of data and the maximum
data size of one CANFD message is 64 bytes, it is divided into two CANFD messages.

3. Converting CAN messages to serial frames
This example configures the CAN message "frame information" conversion and
"frame ID" conversion. Assuming that the frame ID1 in the CAN message is 0x01, the
frame ID0 is 0x23, and the data is 0x12, 0x34, 0x56, 0x78, 0xab, 0xcd, 0xef, 0xff, the CAN
message and the converted serial frame are listed in Table 4.8.
