Remote Frame Transmission - NEC V850ES/F 3-L Series User Manual

CAN Controller (CAN)
Status of TRQ of
ABT message buffer
Set (1)
Cleared (0)
a)
The above resumption operation can be performed only if a message buffer ready for ABT exists in the ABT
area. For example, an abort request that is issued while ABT of message buffer 7 is in progress is regarded
as completion of ABT, rather than abort, if transmission of message buffer 7 has been successfully completed,
even if the ABTTRG bit is cleared to 0. If the RDY bit in the next message buffer in the ABT area is cleared to
0, the internal ABT pointer is retained, but the resumption operation is not performed even if the ABTTRG bit
is set to 1, and ABT ends immediately.

Remote frames can be transmitted only from transmit message buffers. Set
whether a data frame or remote frame is transmitted via the RTR bit of the
CnMCONFm register. Setting (1) the RTR bit sets remote frame transmission.
