Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | b0h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, sub command = F0h |
| 5 | Fun ID=0x02 |
