The User Code register helps to distinguish between the devices built from the same chip. The User Code register value is set through eFuse. Each variant is uniquely identified by feature set or pinned out interface.
The User Code register is a 32-bit register that specifies the version and part number of the component. The content of this register is replicated to the device configuration area that is memory mapped. For details of this register, see Figure 6-7 and Table 6-8.
Field | Width | Description |
---|---|---|
Version | 4 | Revision of the device. This field must change each time that the logic or mask set of the device is revised. The initial value is 0. |
Variant Number | 16 | Variant of chip. The decoding of this field is shown in FCFG1:USER_ID (see Section 11.4). |
Reserved | 11 | 0 |
0 | 1 | Bit 0 is always 1 |
