Messages can use either standard or extended identifiers. Incoming frames are masked
with their appropriate global masks. Bit IDE of the incoming message determines
whether the standard 11-bit mask in Global Mask Short (GMS), or the 29-bit extended
mask in Global Mask Long (UGML&LGML) is to be used. Bits holding a “0” are “don’t
care”, that is, do not compare the message’s identifier in the respective bit position.
The last message object (15) has an additional individually programmable acceptance
mask (Mask of Last Message, UMLM&LMLM) for the complete arbitration field. This
allows classes of messages to be received in this object by masking some bits of the
identifier.
Note: The Mask of Last Message is ANDed with the Global Mask that corresponds to
