Description of DIA_REG Bit7
5.8
The IC's identifier is used for production test purposes and features plug & play functionality depending on the
systems software release. It is made up on a device-number and a revision number each one read-only acces-
sible via standardised instructions.
The Device number is defined once to allow indentification of different IC-Types by software.
The Revision number may be utilised to distinguish different states of hardware. The contents is divided into an
upper 4 bit field reserved to define revisions correspondending to specific softwarereleases. The lower 4 bit field
is utilised to indentify the actual maskset.
Both (SWR and MSR) will start with 0000b and are increased by 1 every time an according modification of the
hardware is introduced.
