(9/23) 3. Operations of the R/W Module 3.1 Outline of operations The R/W Module receives commands from the User board, executes read / write processes on the Tag, and returns a response of the results of the process to the User board. The status of the R/W Module operations will be reflected on the Output / LED.

The Module may be set on either the “Oscillate Mode” “Stop Mode” depending on whether the Module should oscillate while not in communication with the Tag. The “Stop Mode” conserves dissipation power, and enables the R/W Module antenna to be installed close to the Tag to conduct communications on a time sharing basis. The “Oscillate Mode” allows the Module to constantly supply power to the Tag for FIFO processing. Oscillation Status Operation Mode Switching Conditions Stop Mode (conserves The antenna stops • Mode switching conditions at dissipation power) oscillating while not start-up processing commands • When oscillation OFF command is active Oscillation Mode The antenna is • When oscillation ON command (enables high-speed constantly oscillating is active processing) • When option is active in FIFO Trigger / FIFO Auto Command

(10/23) 3.3 Input STOP When a STOP signal is input to the R/W Module, receiving and processing of commands and command processing will stop and then, after the STOP signal is deactivated, the Module will be on stand by for new commands. When the STOP signal is input, oscillation will stop regardless of the setting of the oscillation control mode. If a STOP signal is input more than 50 msec prior to shut down, writing of unstable data to the Tag may be prevented. However, if writing of the command in process requires more than one page, not all pages may be completely rewritten. 3.4 Memory Management on Tag The Tags used to conduct communication with the R/W Module may be one of the following two types depending on memory capacity: 128 bytes (user area 112 bytes) or 256 bytes (user area 240 bytes). The memory area recognizes every 8 bytes as one page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on. n Memory Map (00h ~ EFh indicates to address) Page 8 bytes / page 1 00h 01h 02h 03h 04h 05h 06h 07h 2 08h 09h 0Ah 0Bh 0Ch 0Dh 0Eh 0Fh 3 10h 11h 12h ⋅⋅⋅ ⋅⋅⋅ 17h 4 18h 19h 1Ah ⋅⋅⋅ ⋅⋅⋅ 1Fh 5 20h 27h 6 28h 2Fh 112 bytes 7 30h 37h 8 9 10 : : 11 : : 240 bytes 12 13 14 68h ⋅⋅⋅ ⋅⋅⋅ 6Fh 15 70h ⋅⋅⋅ ⋅⋅⋅ 77h 16 78h ⋅⋅⋅ ⋅⋅⋅ 7Fh : : : : : : 29 E0h E1h ⋅⋅⋅ ⋅⋅⋅ E7h 30 E8h E9h ⋅⋅⋅ ⋅⋅⋅ EFh

(11/23) 3.5 Processing Tag Memory (1) Process Contents The following three processes may be executed on the Tag Memory 1) Read Reading data from Tag Memory. The area to execute the Read command may be selected at random up to 16 pages. 2) Write Writing data onto Tag Memory. The area to execute the Write command may be selected at random up to 16 pages. When writing the same data onto all pages (multiple write), there is no limitation on the number of pages. Certain data within a page may be selected in units of bytes to be written onto the Tag Memory (byte write). 3) Write Protection Set/OFF Write protection may be set on the selected pages of Tag Memory. When write protection is set, the data may be read, but not re-written. Write protection may be set on any of the pages. Write protection may be set or turned off by commands. (2) Communication Operations The following 6 communications operation may be executed by changing the process procedure and execution timing. Communication operations may be specified by commands during command transmission. 1) Single Trigger Communication with Tag will be executed immediately after receiving command and a response will be transmitted. After response is transmitted, the Module will be on stand by for new commands. During communication with the Tag, there may only be one Tag within the communication area. ♦ Operation Sequence Processing will be executed once only after receiving command. If there is no Tag, a Tag absent error message will be transmitted. User → Command Command User ← Response 1 Response 2 (Tag Absence Error) Tag Communication Command Process Command Process Tag Operation Tag 1

(12/23) 2) Single Auto After receiving command, the Module waits for the Tag to approach, communicates with the Tag, and then transmits a response. Once the response is transmitted, Module will be on stand by for new commands. During communication with the Tag, there must be one Tag within the communication area. ♦ Operation Sequence After receiving command, the Module waits for the Tag to approach, then executes process once only after Tag is detected. When Module receives a STOP command, the command will be completed. User → Command Command STOP User ← Response Response Tag Communication Command Process (Truncation Tag Tag Detection Tag Operation Detection Tag 1 Process) 3) FIFO Trigger Module will communicate with Tag immediately after receiving command and transmit response. After communication is completed, Module will prohibit Tag from operating. Module will be on stand by for commands after response is transmitted. During communication with Tag, there MUST BE AN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION) within the communication area. When this command is executed, Module automatically activates “Oscillation Mode” ♦ Operation Sequence Upon receiving command, Module will execute process once only. If there is no Tag, a Tag absence error will be transmitted. During processing of the command, Tag will become inoperative, and thus will not respond to the next command. Oscillation will continue after command is processed.
