Register Function
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 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.
