I2C Command Syntax

I2C input syntax uses "Least Significant Byte First" formatting, which means the data bytes are sent in reverse order:

[Address Byte] [Command Byte] [Data 8] ... [Data 0]

For example, to set the Logic output to Active Low:

0x10 0x06 0x00

Or to set VCOMP to 2650:

0x10 0x02 0x5A 0x0A
