(9/23)3. Operations of the R/W Module3.1 Outline of operationsThe R/W Module receives commands from the User board, executes read / writeprocesses on the Tag, and returns a response of the results of the process to theUser board. The status of the R/W Module operations will be reflected on the Output/ LED.n Operations Timing ChartStatus Initialprocess Waiting forcommand Receivingcommand Processingcommand Transmittingresponse WaitingcommandTXD CommandRXD ResponseTagcommuni-cationsCOMM ↓NORM ↓ERR ↓RUN ↓3.2 Oscillation ControlThe R/W Module supplies power to the Tag by oscillating the antenna, and thusconducts communication with the Tag. The Module may be set on either the“Oscillate Mode” “Stop Mode” depending on whether the Module should oscillatewhile not in communication with the Tag. The “Stop Mode” conserves dissipationpower, and enables the R/W Module antenna to be installed close to the Tag toconduct communications on a time sharing basis. The “Oscillate Mode” allows theModule to constantly supply power to the Tag for FIFO processing.Oscillation Status Operation Mode Switching ConditionsStop Mode (conservesdissipation power) The antenna stopsoscillating while notprocessing commands• Mode switching conditions atstart-up• When oscillation OFFcommand is activeOscillation Mode(enables high-speedprocessing)The antenna isconstantly oscillating • When oscillation ON commandis active• When option is active in FIFOTrigger / FIFO Auto CommandOut-put /LEDPage 1Page 2:Page nUser CPUR/W ModuleTagUser Board
(10/23)3.3 Input STOPWhen a STOP signal is input to the R/W Module, receiving and processing ofcommands and command processing will stop and then, after the STOP signal isdeactivated, the Module will be on stand by for new commands. When the STOPsignal is input, oscillation will stop regardless of the setting of the oscillation controlmode.If a STOP signal is input more than 50 msec prior to shut down, writing of unstabledata to the Tag may be prevented. However, if writing of the command in processrequires more than one page, not all pages may be completely rewritten.3.4 Memory Management on TagThe Tags used to conduct communication with the R/W Module may be one of thefollowing 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 asone page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on.n Memory Map (00h ~ EFh indicates to address)Page 8 bytes / page1 00h 01h 02h 03h 04h 05h 06h 07h2 08h 09h 0Ah 0Bh 0Ch 0Dh 0Eh 0Fh3 10h 11h 12h ⋅⋅⋅ ⋅⋅⋅ 17h4 18h 19h 1Ah ⋅⋅⋅ ⋅⋅⋅ 1Fh5 20h 27h6 28h 2Fh7 30h 37h8910 : :11 : :121314 68h ⋅⋅⋅ ⋅⋅⋅ 6Fh15 70h ⋅⋅⋅ ⋅⋅⋅ 77h16 78h ⋅⋅⋅ ⋅⋅⋅ 7Fh: : :: : :29 E0h E1h ⋅⋅⋅ ⋅⋅⋅ E7h30 E8h E9h ⋅⋅⋅ ⋅⋅⋅ EFh112 bytes240 bytes
(11/23)3.5 Processing Tag Memory(1) Process ContentsThe following three processes may be executed on the Tag Memory1) ReadReading data from Tag Memory. The area to execute the Read commandmay be selected at random up to 16 pages.2) WriteWriting data onto Tag Memory. The area to execute the Write commandmay be selected at random up to 16 pages. When writing the same dataonto 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 writtenonto the Tag Memory (byte write).3) Write Protection Set/OFFWrite protection may be set on the selected pages of Tag Memory. Whenwrite protection is set, the data may be read, but not re-written. Writeprotection may be set on any of the pages. Write protection may be set orturned off by commands.(2) Communication OperationsThe following 6 communications operation may be executed by changing theprocess procedure and execution timing. Communication operations may bespecified by commands during command transmission.1) Single TriggerCommunication with Tag will be executed immediately after receivingcommand and a response will be transmitted. After response is transmitted,the Module will be on stand by for new commands. During communicationwith the Tag, there may only be one Tag within the communication area.♦ Operation SequenceProcessing will be executed once only after receiving command. If there isno Tag, a Tag absent error message will be transmitted.TagCommunicationTag 1Tag OperationUser ←User →Command CommandResponse 2(Tag Absence Error)Command ProcessCommand ProcessResponse 1
(12/23)2) Single AutoAfter receiving command, the Module waits for the Tag to approach,communicates with the Tag, and then transmits a response. Once theresponse is transmitted, Module will be on stand by for new commands.During communication with the Tag, there must be one Tag within thecommunication area.♦ Operation SequenceAfter receiving command, the Module waits for the Tag to approach, thenexecutes process once only after Tag is detected. When Module receives aSTOP command, the command will be completed.3) FIFO TriggerModule will communicate with Tag immediately after receiving commandand transmit response. After communication is completed, Module willprohibit Tag from operating. Module will be on stand by for commands afterresponse is transmitted. During communication with Tag, there MUST BEAN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROMOPERATION) within the communication area. When this command isexecuted, Module automatically activates “Oscillation Mode”♦ Operation SequenceUpon receiving command, Module will execute process once only. If thereis no Tag, a Tag absence error will be transmitted. During processing of thecommand, Tag will become inoperative, and thus will not respond to thenext command. Oscillation will continue after command is processed.Tag 1TagCommunicationTag Operation User ←User →Command Command(Tag Absence Error)Command ProcessCommand Process(Oscillation)(Oscillation)Response 2Response 1ResponseTagCommunicationTag 1Tag OperationUser ←User →CommandCommandSTOP(TruncationProcess)Tag DetectionTagDetectionCommand ProcessResponse
(13/23)4) FIFO AutoModule will await Tag to approach after receiving command, thencommunicate with Tag and transmit response. After communication iscompleted, Module will prohibit Tag from operating. Module will be on standby after response transmission is completed. During communication withthe Tag, there MUST BE AN OPERATIONAL TAG (A TAG THAT IS NOTPROHIBITED FROM OPERATION) within the communication area. Whenthis command is executed, Module automatically activates “OscillationMode.”♦ Operation SequenceAfter receiving command, the Module waits for the Tag to approach, thenexecutes process once only after Tag is detected. During processing of thecommand, Tag will become inoperative, and thus will not respond to thenext command. Oscillation will continue after command is processed.When Module receives a STOP command, the command will becompleted.5) FIFO ContinueAfter receiving command, the Module waits for the Tag to approach, thencommunicates with the Tag and transmits a response. After communicationis completed, Tag will become inoperative. After transmitting a response,Module will await Tag to approach again if it receives [ACK], andCONTINUE UNTIL MODULE RECEIVES A STOP COMMAND. Whencommunicating with the Tag, THERE MUST ONLY BE ONE ACTIVE TAGwithin the communication area.♦ Operation SequenceUpon receiving the command, Module awaits Tag to approach. When Tagis detected, Module executes command and transmits a response.Afterwards, when [ACK] is received, Module repeats the same operation.Once process is executed on a Tag, the Tag becomes inoperative, and thusa Tag will only be processed once. When Module receives a STOPcommand, processing will stop.(Oscillation)Tag 1Command CommandResponseSTOPResponse 11TagCommunicationTag OperationUser ←User →Tag DetectionTagDetectionCommand Process(TruncationProcess)(Oscillation)Tag 2Tag 1Command STOPNACKACKResponse 2Response 2Response 1TagDetectionTagDetectionTagCommunicationTag OperationUser ←User →Command ProcessCommand Process(Oscillation)
(14/23)6) FIFO RepeatAfter receiving command, the Module waits for the Tag to approach, thencommunicates with the Tag and transmits a response. After communicationis completed, Tag will become inoperative. MODULE WILL CONTINUEPROCESS UNTIL IT RECEIVES A STOP COMMAND. Whencommunicating with the Tag, THERE MUST ONLY BE ONE ACTIVE TAG(A TAG THAT IS NOT PROHIBITED FROM OPERATION) within thecommunication area.♦ Operation SequenceUpon receiving the command, Module awaits Tag to approach. When Tagis detected, Module executes command and transmits a response.Afterwards, Module repeats the same operation. Once process is executedon a Tag, the Tag becomes inoperative, and thus a Tag will only beprocessed once. When Module receives a STOP command, processing willstop.4.
