* Abbreviation
This document refers to the differential signals in unipolar shorthand; for example, SCL_IN, SDA_IN, SCL_OUT, and
SDA_OUT mean (SCL_INp - SCL_INn), (SDA_INp - SDA_INn), (SCL_OUTp - SCL_OUTn), and (SDA_OUTp -
SDA_OUTn) respectively.
* A falling transition of the SDA_IN while the SCL_IN is high is defined as ”Header Condition“. Please refer to the sec-
tion “2-pair Serial LVDS Input” for details.
