b0011(3) = write request with Option "1"
The Reader tries to sample the response after ISO15693-3 T1 ( 318,6µs ....
323,3µs), if there is no response the Reader sends a EOF after EOF-PULSE-DELAY
and tries to sample the response after ISO15693-3 T1 ( 318,6µs .... 323,3µs)
b0100(4) = inventory request
The Reader tries to sample the response after ISO15693-3 T1 ( 318,6µs ....
323,3µs). If ISO15693 "Nb_slot_flag" Flag is:
b0101(5) = write request with Option "0" and grid position of response
The Reader tries to sample the response after ISO15693-3 T1 ( 318,6µs ....
323,3µs). If there is no response the Reader tries to sample at the time/grid specified
in MULTIPLE 302us GRIDS. If there is no response the command sends back
Status "no. Transponder" [0x01].
Depending on the ERROR_Flag in the Transponder response the length of the sam-
pled data is:
HDR_RL: (from firmware version 1.04.06)
b0 Switch off use of High Data Rate(53kBit/s) for Return Link
b1 Switch on use of High Data Rate(53kBit/s) for Return Link
RSP-LENGTH:
Length of the Transponder response in bit without SOF and EOF. During write operations
REP-LENGTH is depending on ERROR_FLAG in the Transponder response:
- 4 Byte if ERROR_FLAG is "1".
- – REP-LENGTH if ERROR_FLAG is "0"
reserved (CMD-RSP-DELAY)
In MR/PR/PRH protocol not used. To avoid problems with other OBID
should be value of response delay for Transponder response (ISO15693: t1)
e.g. ISO15693 average value: 0x021F * 590ns = 320,9µs

System-Manual
"0" the Reader sends a EOF after EOF-PULSE-DELAY and tries again to sam-
ple the response in the next timeslot ( after ISO15693-3 T1 ( 318,6µs
.... 323,3µs)). This is done 16 times.
In this case the RSP-LENGTH defines the response length in one time-
slot. Transponder responses with other response length will be ignored.
If there is a CRC error in one of the timeslots the protocol status is set
to 0x02 [CRC error]. The user should calculate which Transponder data
hold the CRC error.
"1" the Reader sends back the received data.
4 Byte if ERROR_FLAG is "1".
