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.
DynID_x[5:0]: Dynamically assigned LIN identifier to the application command which ROM pointer is ROMp_x[3:0].
One frame allows only assigning four identifiers. Therefore, additional frames could be needed in order to assign more identifiers
(maximum three for the AMIS-30621).
