26.5.2.68 Message Buffer Configuration, Control, Status Registers (MBCCSRn)
The content of these registers comprises message buffer configuration data, message buffer control data,
message buffer status information, and message buffer interrupt flags. A detailed description of all flags
can be found in Section 26.6.6, Individual Message Buffer Functional Description.
If the application writes 1 to the EDT bit, no write access to the other register bits is performed.
If the application writes 0 to the EDT bit and 1 to the LCKT bit, no write access to the other bits is
performed.
