23.15.24 IF3 Update Enable Registers (CAN IF3UPD)

The automatic update functionality of the IF3 register set can be configured for each message object. A
message object is enabled for automatic IF3 update, if the dedicated IF3UpdE flag is set. This means that
an active NewDat flag of this message object (e.g due to reception of a CAN frame) will trigger an
automatic copy of the whole message object to IF3 register set.
NOTE: IF3 Update enable should not be set for transmit objects.
