1762 Terminology (Informational)

177The MIPI Alliance has adopted Section 13.1 of the IEEE Standards Style Manual, which dictates use of the

178words “shall”, “should”, “may”, and “can” in the development of documentation, as follows:

179The word shall is used to indicate mandatory requirements strictly to be followed in order to conform to the

180standard and from which no deviation is permitted (shall equals is required to).

181The use of the word must is deprecated and shall not be used when stating mandatory requirements; must is

182used only to describe unavoidable situations.

183The use of the word will is deprecated and shall not be used when stating mandatory requirements; will is

184only used in statements of fact.

185The word should is used to indicate that among several possibilities one is recommended as particularly

186suitable, without mentioning or excluding others; or that a certain course of action is preferred but not

187 necessarily required; or that (in the negative form) a certain course of action is deprecated but not

188prohibited (should equals is recommended that).

189The word may is used to indicate a course of action permissible within the limits of the standard (may

190equals is permitted).

191The word can is used for statements of possibility and capability, whether material, physical, or causal (can

192equals is able to).

193All sections are normative, unless they are explicitly indicated to be informative.

1942.1 Definitions

195Forward Direction: The signal direction is defined relative to the direction of the high-speed serial clock.

196Transmission from the side sending the clock to the side receiving the clock is the forward direction.

197Half duplex: Bidirectional data transmission over a Lane allowing both transmission and reception but

198only in one direction at a time.

199HS Transmission: Sending one or more packets in the forward direction in HS Mode. A HS Transmission

200is delimited before and after packet transmission by LP-11 states.

201Host Processor: Hardware and software that provides the core functionality of a mobile device.

202Lane: Consists of two complementary Lane Modules communicating via two-line, point-to-point Lane

203Interconnects. A Lane is used for either Data or Clock signal transmission.

204Lane Interconnect: Two-line point-to-point interconnect used for both differential high-speed signaling

205and low-power single ended signaling.

206Lane Module: Module at each side of the Lane for driving and/or receiving signals on the Lane.

207Link: A complete connection between two devices containing one Clock Lane and at least one Data Lane.

208LP Transmission: Sending one or more packets in either direction in LP Mode or Escape Mode. A LP

209Transmission is delimited before and after packet transmission by LP-11 states.
