Register 1: Device Identification 0 (DID0), offset 0x000
This register identifies the version of the microcontroller. Each microcontroller is uniquely identified
by the combined values of the CLASS field in the DID0 register and the PARTNO field in the DID1
register.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

DID0 Version
This field defines the DID0 register format version. The version number
is numeric. The value of the VER field is encoded as follows:

Device Class
The CLASS field value identifies the internal design from which all mask
sets are generated for all devices in a particular product line. The CLASS
field value is changed for new product lines, for changes in fab process
(for example, a remap or shrink), or any case where the MAJOR or MINOR
fields require differentiation from prior devices. The value of the CLASS
field is encoded as follows (all other encodings are reserved):
DescriptionValue
Stellaris® Fury-class devices.0x1
