Description Of Common Commands

Figure 3-1 shows the common commands and queries. These commands are listed alphabetically in the dictionary. If a command has a corresponding query that simply returns the data or status specified by the command, then both command and query are included under the explanation for the command. If a query does not have a corresponding command or is functionally different from the command, then the query is listed separately. The description for each common command or query specifies any status registers affected. In order to make use of this information, you must refer to "Chapter 4 - Status Reporting", which explains how to read specific register bits and use the information that they return.
