+## 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
+```
