Figure 5-81 Data transfer between IFn Registers and Message
After a partial write of a Message Object, the Message Buffer Registers that are not selected in
the Command Mask Register will set the actual contents of the selected Message Object.
After a partial read of a Message Object, the Message Buffer Registers that are not selected in
the Command Mask Register will be left unchanged.
5.13.6.2.2 Message Transmission
If the shift register of the CAN Core cell is ready for loading and if there is no data transfer
between the IFn Registers and Message RAM, the MsgVal bits in the Message Valid Register
and TxRqst bits in the Transmission Request Register are evaluated. The valid Message Object
