New Data Register 1 (CAN_NDAT1)
These registers hold the NewDat bits of the 32 Message Objects. By reading out the NewDat
bits, the software can check for which Message Object the data portion was updated. The
NewDat bit of a specific Message Object can be set/reset by the software through the IFn
Message Interface Registers or by the Message Handler after reception of a Data Frame or after
a successful transmission.
