Shorthand Notations. The notation “DS315x” throughout this data sheet refers to either the DS3151, DS3152,

DS3153, or DS3154. This data sheet is the specification for all four parts. The LIUs on the DS315x are identical.

For brevity, this document uses the pin name and register name shorthand “NAMEn,” where “n” stands in place of

the LIU port number. For example, on the DS3154 quad LIU, TCLKn is shorthand notation for pins TCLK1, TCLK2,

TCLK3, and TCLK4 on LIU ports 1, 2, 3, and 4, respectively. This document also uses generic pin and register

names such as TCLK (without a number suffix) when describing LIU operation. When working with a specific LIU

on the DS315x devices, generic names like TCLK should be converted to actual pin names, such as TCLK1.
