Software Information Block registers are read-only.
6.2.1
SW Part Number
Software part number is a 14 characters ASCII string formatted according to Cattron standard part number format;
[4 digits prefix]-[4 digits number]-[4 digits suffix]. Example: “3SOF-7954-A001”
6.2.2
SW Revision
Software revision is given by 3 segments separated by commas. The segments are typically but not restricted to
numbers. Ex: “3.12.7”, “1.2.7B”,
numbers. Ex: “3.12.7”, “1.2.7B”,
A 10 characters long field is defined..
6.2.3
Register Map Version number
This is number is represented by numerical values. Ex: 1.34;
- The second segment is incremented each time new registers are added to the Register map, and this addition has
no impact on backward compatibility. It is encoded on in the LSB.
- The first segment is incremented each time a change to the Register Map has any impact on backward
compatibility. It is encoded in the MSB.
- The second segment is incremented each time new registers are added to the Register map, and this addition has
no impact on backward compatibility. It is encoded on in the LSB.
- The first segment is incremented each time a change to the Register Map has any impact on backward
compatibility. It is encoded in the MSB.
For example, “1.34” would be encoded as 0x0122.
