There are reserved bits. These bits are always read as ‘0’ and must always be written
with ‘0’.
Write / Read
1 = Write: Transfer data from the selected Message Buffer Registers to the Message
0 = Read: Transfer data from the Message Object addressed by the Command Request
Access Mask Bits
Direction = Write
1 = Transfer Identifier Mask + MDir + MXtd to Message Object.
0: = Mask bits unchanged.
Direction = Read
1 = Transfer Identifier Mask + MDir + MXtd to IFn Message Buffer Register.
0 = Mask bits unchanged.
Access Arbitration Bits
Direction = Write
1 = Transfer Identifier + Dir + Xtd + MsgVal to Message Object
0 = Arbitration bits unchanged.
Direction = Read
1 = Transfer Identifier + Dir + Xtd + MsgVal to IFn Message Buffer Register.
0 = Arbitration bits unchanged.
Object addressed by the Command Request Register.
Register into the selected Message Buffer Registers.
