Type #8: eight data bytes preparing frame with 0x3C identifier.
Where:
AppCMD: If = ‘0x80’ this indicates that Data 2 contains an application command

AD[6:0]: Slave node physical address

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
Where:
One frame allows only assigning of four identifiers. Therefore, additional frames could be needed in order to assign more
identifiers (maximum three for the AMIS−30623).

The identifier field in the LIN datagram denotes the

Broad: If <Broad> = ‘0’ all the circuits connected to the LIN bus will share the same dynamically assigned identifiers.
Dyn_ID_x [5:0]: Dynamically assigned LIN identifier to the application command which ROM pointer is <ROMp_x [3:0]>

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.
