23.6.10 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 transmission RTR register (TRTRR) is 0).
0: Transmission starts immediately
1: Transmission starts after waiting until remote frame received (remote request receive 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.
23.6.11 Transmission Cancel Register (TCANR)
When 1 is written to TCANx, this register cancels a pending request for transmission to the message buffer
(x).
At completion of cancellation, TREQx of the transmission request register (TREQR) becomes 0. Writing 0 to
TCANx is ignored.
This is a write-only register and its read value is always 0.
