NOTICE: This related information is not an official part of SEMI E99.1. This related information was approved for
publication by full letter ballot procedures on January 14, 2000.
This section provides examples of typical scenarios for a Carrier ID Reader/Writer.
R1-1 Read ID
R1-1.1 The upstream controller sends a Read ID Request message to the CIDRW for Head 1. The CIDRW Head 1
reads the ID, and the CIDRW returns the ID to the upstream controller.

Read ID Scenario
R1-2 Read Data
R1-2.1 The upstream controller sends a Read Data Request message to the CIDRW for Head 1 and DataSeg 1. The
CIDRW Head 1 reads the data, and the CIDRW returns the data to the upstream controller.

Read Data Scenario
R1-3 Write ID
R1-3.1 The CIDRW is in IDLE. The upstream controller requests the CIDRW change its operational status to
MAINTENANCE.
R1-3.2 The CIDRW changes to MAINTENANCE and replies that it has changed state.
R1-3.3 The upstream controller sends a Write ID Request message to the CIDRW for Head 1. The CIDRW Head 1
reads the ID, and the CIDRW returns the ID to the upstream controller.
