9.2.3 Device Identifier and Revision
The IC’s identifier (device ID) and revision number are used for production test purposes and features plug & play
functionality depending on the systems software release. The two numbers are read-only accessible via the SPI-
instructions RD_ID and RD_REV as described in Section 9.2.1. The device ID is defined to allow identification of
different IC-types by software and is fixed for the TLE8209-2.
The revision number may be utilized to distinguish different states of hardware and is updated with each redesign
of the TLE8209-2. It is divided into an upper 4 bit field reserved to define revisions (SWR) corresponding to specific
software releases and a lower 4 bit field utilized to identify the actual mask set revision (MSR).
