By means of a remote frame, the software may request another CAN node to provide new data for a receive object. Setting the TxRqst bit of a receive object will cause the transmission of a remote frame with the identifier of the receive object. This remote frame triggers the other CAN node to start the transmission of the matching data frame. If the matching data frame is received before the remote frame could be transmitted, the TxRqst bit is automatically reset. Setting the TxRqst bit without changing the contents of a message object requires the value 0x84 in bits [23:16] of the command register (DCAN_IF1CMD/ DCAN_IF2CMD).
