21.2.3 CAN Message Object Registers
Each message object is provided with a set of control and data register. The
corresponding register names are supplemented with a variable n running from 0 to 31
(e.g. MSGDRn0 means that data register MSGDR300 is assigned with message object
number 30).
The Message Data Register 0 contains the data bytes 0 to 3 of message object n.
MSGDRHn0 (n = 31-0)
Message Object n Data Register 0 High
MSGDRLn0 (n = 31-0)
Message Object n Data Register 0 Low
