Data-byte: Device Identifier and Version
(SPI instructions RD_IDENT and RD_VERSION)
The IC‘s identifier (device ID) and version 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_IDENT and
RD_VERSION as described in Section 2.4.2.4.
The device ID is defined to allow identification of different IC-Types by software and is
fixed for the TLE 7209R.
The Version number may be utilized to distinguish different states of hardware and is
updated with each redesign of the TLE 7209R. The contents 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).
Both (SWR and MSR) will start with 0000b and are increased by 1 every time an
according modification of the hardware is introduced.
