Remote Frame Receiving Wait Register (RFWTR)
Remote frame receiving wait register (RFWTR) stores the conditions for starting
transmission when a request for data frame transmission is set (TREQx of the
transmission request register (TREQR) is "1" and TRTRx of the transmitting RTR
register (TRTRR) is "0").

[bit15 to bit0] RFWT15 to RFWT0:
"0": Transmission starts immediately
"1": Transmission starts after waiting until remote frame received (RRTRx of remote request receiving
register (RRTRR) becomes "1")
Notes:
• Transmission starts immediately if RRTRx is already "1" when a request for transmission is set.
• For remote frame transmission, do not set RFWTx to "1".
