 Numpy scalars behave like plain Python numbers in arithmetic, comparison and formatting. Use `int()` or `float()` where a built-in type is required.
 
+## Reading an address no schema describes
+
+A register class is normally declared with its address, as above, or generated from a `device.yml`. Calling a register base with an address instead builds a one-off register for that address, which is how a payload outside any schema is read and written:
+
+```python
+from harp.protocol import RegisterU8Array, RegisterU16
+
+uid = RegisterU8Array(0x10, length=16)   # R_UID, named by no schema
+tag = RegisterU8Array(0x11, length=16)   # R_TAG, the firmware git hash
+version = RegisterU16(0x08)              # any address, as a scalar
+```
+
+The result is an ordinary register, so it goes through `read` and `write` on a device exactly as a declared one does. `length` is keyword-only for the array form, and it is the element count rather than a byte count. An already-addressed register rejects the call, so `WhoAmI(44)` raises rather than quietly producing a register at another address.
+
 It carries no transport or device logic. See [`harp-device`](https://github.com/harp-tech/python/tree/main/src/packages/harp-device) for the device layer.

 Passing a device module validates the device identity on open. Pass a `Device` subclass instead to preserve its own type, or omit the argument entirely for schema-free access, which skips the identity check.
