CHAPTER 23 CAN CONTROLLER
23.6.15
Remote Request Receiving Register (RRTRR)
After a remote frame is stored in the message buffer (x), RRTRx becomes "1" (at the
same time as RCx setting to "1").
■ Remote Request Receiving Register (RRTRR)
Figure 23.6-18 Configuration of the Remote Request Receiving Register (RRTRR)
[bit15 to bit0] RRTR15 to RRTR0:
●
Conditions for RRTRx = 0
• Write "0" to RRTRx.
• After a received data frame is stored in the message buffer (x) (at the same time as RCx setting to "1").
• Transmission by the message buffer (x) is completed (TCx of the transmission complete register (TCR)
is "1").
Writing "1" to RRTRx is ignored.
"1" is read when a Read Modify Write (RMW) instruction is performed.
Note:
If setting to "1" by completion of the receive operation and clearing to "0" by writing occur at the
same time, the bit is set to "1".
