Selection of Message Object Number
The available numbers are: 0 to 14 (see Figure 48).
Auto Increment of the Index (active low)
0 - auto-increment of the index (default value).
1 - non-auto-increment of the index.
Index
Byte location of the data field for the defined message object (see Figure 48).
Configuration of Message Object
CONCH1 CONCH0
Note: The user must re-write the configuration to enable the corresponding bit
in the CANEN1:2 registers.
Reply Valid
Used in the automatic reply mode after receiving a remote frame
0 - reply not ready.
1 - reply ready and valid.
Identifier Extension
0 - CAN standard rev 2.0 A (ident = 11 bits).
1 - CAN standard rev 2.0 B (ident = 29 bits).
Data Length Code
Number of Bytes in the data field of the message.
The range of DLC is from 0 up to 8.
This value is updated when a frame is received (data or remote frame).
If the expected DLC differs from the incoming DLC, a warning appears in the
CANSTCH register.
