23.1.20.7 RECREQ Bit
23.1.20.8 TRMREQ Bit
The RECREQ bit determines transmit/receive mode shown in Table 23.4. When the RECREQ bit is set to 1
(receive operation requested), the message slot is set to receive the data frame or remote frame. If the REMOTE
bit is set to 1 (remote frame transmitted/received) and the RSPLOCK bit is set to 0 (automatic answering to the
remote frame enabled), the data frame is transmitted automatically after the remote frame is received,
regardless of the RECREQ bit setting to 0.
Set the RECREQ bit to 0 (receive operation not requested) to transmit the data frame or remote frame.
Do not set both the TRMREQ and RECREQ bits in the same message slot to 1.
The TRMREQ bit determines transmit/receive mode shown in Table 23.4. When the TRMREQ bit is set to 1
(transmit operation requested), the data frame or remote frame is transmitted. If the REMOTE bit is set to 0
(remote frame transmitted/received), the message slot automatically switches to a receive slot for the data frame
after the remote frame is transmitted, regardless of the TRMREQ bit setting to 1.
Set the TRMREQ bit to 0 (transmit operation not requested) to receive the data frame or remote frame.
Do not set both the TRMREQ and RECREQ bits in the same message slot to 1.
NOTES:
