7. Revision Specific Behavior
This chapter details any known differences from behavior as stated in the device datasheet and reference manual.
All known errata for the current silicon revision are rolled into this section at the time of publication. Any errata
found after publication of this document will initially be detailed in a separate errata document until this datasheet is
revised.
7.1. Revision Identification
The Lot ID Code on the top side of the device package can be used for decoding device revision information.
Figures 7.1, 7.2, 7.3, and 7.4 show how to find the Lot ID Code on the top side of the device package.
In addition, firmware can determine the revision of the device by checking the DEVICEID registers.
