Checksum
Checksum over data
Where :
CMD[6:0]: 0x11, corresponding to dynamic assignment of four LIN identifiers
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]>
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 ? 30621).
