content of the message. Six identifier bits and two parity bits
are used to represent the content. The identifiers 0x3C and
0x3F are reserved for command frames and extended
frames. Slave nodes need to be very flexible to adapt itself
to a given LIN network in order to avoid conflicts with slave
nodes from different manufacturers. Dynamic assignment
of the identifiers will fulfill this requirement by writing
identifiers into the circuits RAM. ROM pointers are linking
commands and dynamic identifiers together. A writing

frame with identifier 0x3C issued by the LIN master will
write dynamic identifiers into the RAM. One writing frame
is able to assign 4 identifiers; therefore 3 frames are needed
to assign all identifiers. Each ROM pointer <ROMp_x
[3:0]> place the corresponding dynamic identifier
<Dyn_ID_x [5:0]> at the correct place in the RAM (see
Table below: LIN – Dynamic Identifiers Writing Frame).
each slave on the LIN bus will store the same dynamic
identifiers, otherwise only the slave with the corresponding
slave address is programmed.
