## I2C Command Syntax
I2C input syntax uses "Least Significant Byte First" formatting, which means the data bytes are sent in reverse order:
```serial
[Address Byte] [Command Byte] [Data 8] ... [Data 0]
```
For example, to set the Logic output to Active Low:
```serial
0x10 0x06 0x00
```
Or to set VCOMP to 2650:
```serial
0x10 0x02 0x5A 0x0A
```
