(1) TR (Transmit request) bit (D0)
Set this bit to 1 when using the message slot as a transmit slot.
Set this bit to 0 when using the message slot as a data frame or remote frame receive slot.
(2) RR (Receive request) bit (D1)
Set this bit to 1 when using the message slot as a receive slot.
Set this bit to 0 when using the message slot as a data frame or remote frame transmit slot.
If both the TR (Transmit request) and RR (Receive request) bits are set to 1, device operation is
instable.
(3) RM (Remote) bit (D2)
Set this bit to 1 when using the message slot to handle remote frames.
The message slot may be set to handle remote frames in following two ways.
•
Set for remote frame transmission
The data stored in the message slot is transmitted as a remote frame. When transmission
is finished, the slot automatically changes to a data frame receive slot.
However, if a data frame is received before the CAN module finished sending the remote
frame, the received data is stored in the message slot and the remote frame is not
transmitted.
•
Set for remote frame reception
The message slot receives a remote frame. The processing performed after reception
depends on how the RL (Automatic answering disable) bit is set.
(4) RL (Automatic answering disable) bit (D3)
This bit is effective when the message slot has been set as a remote frame receive slot. It selects
the processing to be performed after receiving a remote frame.
Setting this bit to 0 enables automatic answering so that after receiving a remote frame, the
message slot automatically changes to a transmit slot and the data stored in it is transmitted as a
data frame.
When this bit is set to 1, the message slot becomes inactive after receiving a remote frame.
Note: This bit must always be set to 0 unless the message slot is set for remote frame
reception.
