The global layout of the Receive Buffer is very similar to the Transmit Buffer described in the previous chapter. The
Receive Buffer is the accessible part of the RXFIFO and is located in the range between CAN Address 96 and 108. Each
message is subdivided into a Descriptor and a Data Field.

Note that message 2 should not be read until it has been shifted to address 96 by a Release Receive
Buffer Command because this message may be in process now and due to this not fixed.
Message 1 is now available in the Receive Buffer
