+The bytes in this register specify the [semantic version](https://semver.org/) of different device components. Each component version is made up of three bytes, following the order `major`, `minor`, `patch`. The register also includes a unique identifier of the core microcontroller SDK and a hash digest of the interface schema file describing the device capabilities.
+
+* **PROTOCOL:** The semantic version of the Harp protocol implemented by the device.
+
+* **FIRMWARE:** The semantic version of the device firmware application.
+
+* **HARDWARE:** The semantic version of the device hardware.
+
+* **SDK_ID:** The three-character code of the core microcontroller SDK used to implement the device.
+
+* **INTERFACE_HASH:** The SHA-1 hash value of the device interface schema file (`device.yml`). The byte-order is little-endian.
