Message Object in the Message Memory
There are 32 Message Objects in the Message RAM. To avoid conflicts between application
software access to the Message RAM and CAN message reception and transmission, the CPU
cannot directly access the Message Objects, these accesses are handled through the IFn
Interface Registers. Table 5-20 provides an overview of the structures of a Message Object.
UMask
MsgVal
The Arbitration Registers ID28-0 , Xtd , and Dir are used to define the identifier and type of
outgoing messages and are used (together with the mask registers Msk28-0 , MXtd , and MDir) for
acceptance filtering of incoming messages. A received message is stored in the valid Message
Object with matching identifier and Direction = receive (Data Frame) or Direction = transmit
(Remote Frame). Extended frames can be stored only in Message Objects with Xtd = one,
standard frames in Message Objects with Xtd = zero. If a received message (Data Frame or
Remote Frame) matches with more than one valid Message Object, it is stored into that with
the lowest message number.
Message Handler Registers
All Message Handler registers are read-only. Their contents ( TxRqst , NewDat , IntPnd , and
MsgVal bits of each Message Object and the Interrupt Identifier) are status information provided
by the Message Handler FSM.
