23.1.20.7 RECREQ Bit
23.1.20.8 TRMREQ Bit
5
The RECREQ bit selects transmit/receive mode shown in Table 23.4. Set the RECREQ bit to "1"
(receive requested) when data frame or remote frame is received. Set the RECREQ bit to "0" (no
receive requested) when data frame or remote frame is transmitted.
When a data frame is automatically transmitted after a remote frame is received, the RECREQ bit
remains set to "1". Set the RECREQ bit to "0" to transmit a remote frame. After a remote frame is
transmitted, a data frame is automatically received while the RECREQ bit remains set to "0".
When setting the TRMREQ bit to "1" (transmit requested), do not set the RECREQ bit to "1" (receive
requested).
The TRMREQ bit selects transmit/receive mode shown in Table 23.4. Set the TRMREQ bit to "1"
(transmit requested) when data frame or remote frame is transmitted.
Set the TRMREQ bit to "0" (no request to transmit the frame) when data frame or remote frame is
received.
When the data frame is automatically received after the remote frame is transmitted, the TRMREQ bit
remains set to "1". Set the TRMREQ bit to "0" to receive the remote frame. After the remote frame is
received, data frame is automatically transmitted while the TRMREQ bit remains set to "0".
If the RECREQ bit is set to "1" (request to receive the frame), do not set the TRMREQ bit to "1" (
request to transmit the frame).
