For transmission, data is transmitted according to the data byte count set in the
[CANxMBnTSVMCF]<DLC[3:0]> of the mailbox.
For reception, the data length code in the received message is copied to the [CANxMBnTSVMCF]<DLC[3:0]> of
the mailbox, and the data byte count only set in the [CANxMBnTSVMCF]<DLC[3:0]> is made valid.
Mailboxes are readable and writable, but do not write data fields for receive mailboxes. If data fields are written, a
mismatch may occur in received data.
To update the data field of a transmission mailbox set to [CANxMBnID]<RFH>=1, set [CANxCDR]<CDRn> to
"1" and suspend transmission requests temporarily before writing new data. To update the data field of a
transmission mailbox set to [CANxMBnID]<RFH>=0, check that the [CANxTRS]<TRSn> bit is "0" before
writing new data.
