Description
Transmit Interrupt Enable
0: The IntPnd bit in the CANIFnMCTL register is unchanged after a
successful transmission of a frame.
1: The IntPnd bit in the CANIFnMCTL register is set after a successful
transmission of a frame.
Receive Interrupt Enable
0: The IntPnd bit in the CANIFnMCTL register is unchanged after a
successful reception of a frame.
1: The IntPnd bit in the CANIFnMCTL register is set after a successful
reception of a frame.
Remote Enable
0: At the reception of a Remote Frame, the TxRqst bit in the
CANIFnMCTL register is left unchanged.
1: At the reception of a Remote Frame, the TxRqst bit in the
CANIFnMCTL register is set.
Transmit Request
0: This message object is not waiting for transmission.
1: The transmission of this message object is requested and is not yet
done.
End of Buffer
0: Message object belongs to a FIFO Buffer and is not the last message
object of that FIFO Buffer.
1: Single message object or last message object of a FIFO Buffer.
This bit is used to concatenate two or more message objects (up to 32)
to build a FIFO buffer. For a single message object (thus not belonging
to a FIFO buffer), this bit must be set to 1.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Data Length Code
Value Description
0x0-0x8 Specifies the number of bytes in the Data Frame.
0x9-0xF Defaults to a Data Frame with 8 bytes.
The DLC bit in the CANIFnMCTL register of a message object must be
defined the same as in all the corresponding objects with the same
identifier at other nodes. When the message handler stores a data frame,
it writes DLC to the value given by the received message.
