Command messages sent to the device appear to be a sequence of 16-bit words with little endian byte order. The first word in a message identifies the command type. Different command types have different message lengths. Some command types include a length field and allow for messages of variable length, others are of fixed size.
There are read commands which trigger an immediate response from the device, and write commands without a response.
Command 0001: Read Register
This command appears to read a 32-bit wide control register.
Command
Fixed length of 2 words (4 bytes).
| ID | Address |

Response
The response has a fixed length of two words. It is likely the content of a 32-bit register in either little endian or mixed endian byte order.
