MM912_634 analog die Silicon Revision Register Full Mask Revision - The three bits represent the revision count of full
mask change. Read only, writing will have no effect. The first Full Mask will have the count 00.
MM912_634 analog die Silicon Revision Register Metal Tweak Revision - The three bits represent the count of metal
tweaks applied to the full mask.Read only, writing will have no effect. The first Full Mask will have the count 00.
Please refer to the MM912F634ER - Mask set errata document for details on the analog die
mask revisions.
This document will describe the features and functions of option 1 (all modules available and
tested). Beyond this chapter, there will be no additional note or differentiation between the
different implementations.
