Bit name
RRTR7 to 0:
These bits indicate that the message buffer (x) receives a remote
Remote frame receive
frame.
bits 7 to 0
When remote frame is received: 1 is set to the RRTRx bit
corresponding to the message buffer (x) that receives a remote
frame.
When set to 0: Clears bits when receiving already completed
When set to 1: No effect

Function
Setting the RRTRx bit when a remote frame is received
(RRTRx = 1) overrides clearing of the RRTRx bit when 0 is
written (RRTRx = 0) if both occur at the same time.
The RRTRx bit corresponding to the message buffer (x) that
receives a data frame is cleared (RRTRx = 0).
If message transmitting is completed (TCR: TCx = 1), the
RRTRx bit corresponding to the message buffer (x) that
transmits the message is cleared (RRTRx = 0).
