Figure 20-39 shows the processing for a receive message buffer (C0MCONFm.MT2 to C0MCONFm.MT0 bits = 001B
Notes 1. If redefinition is performed during a message reception, confirm that a message is being received
2. This 4-bit period may redefine the message buffer while a message is received and stored.
because the RDY bit must be set after a message is completely received.
