to store data in the message buffer and at the end of this storing processing. During this storing processing, the
C0MCTRLm.MUC bit of the message buffer is set (1) (refer to Figure 20-29).
CPU is prohibited from rewriting the C0MCTRLm.RDY bit of the message buffer in which the data is to be stored.
Completion of this data storing processing may be delayed by a CPU’s access to any message buffer.
