Table 23-49. IF1MCTL Register Field Descriptions (continued)
Bit Field Type Reset Description
10 RxIE R/WP 0h
Receive interrupt enable
0x0 = IntPnd will not be triggered after the successful reception of a
frame.
0x1 = IntPnd will be triggered after the successful reception of a
frame.
9 RmtEn R/WP 0h
Remote enable
0x0 = At the reception of a remote frame, TxRqst is not changed.
0x1 = At the reception of a remote frame, TxRqst is set.
8 TxRqst R/WP 0h
Transmit request
0x0 = This message object is not waiting for a transmission.
0x1 = The transmission of this message object is requested and is
not yet done.
7 EoB R/WP 0h Data frame has 0 to 8 data bits.
Note: This bit is used to concatenate multiple message objects to
build a FIFO Buffer.
For single message objects (not belonging to a FIFO Buffer), this bit
must always be set to one.
0x0 = Data frame has 8 data bytes.
0x1 = Note: The data length code 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 will write the DLC to the value given by the received
message.
6-4 Reserved R/WP 0h
3-0 DLC R/WP 0h Data length code.
Note: The data length code 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 will write the DLC
to the value given by the received message.
0x0 to 0x8 = Data frame has 0 to 8 data bytes.
0x9 to 0x15 = Data frame has 8 data bytes.
