Start up

120 µs after entering the powering field (after the field reset) the SLE 66R01P and SLE 66R01PN is ready to

receive a command. If a command is send earlier, the response to this command is not defined.

7.3.1

Start-up sequence of the SLE 66R01P and SLE 66R01PN

Each time after the execution of a REQA or WUPA, the SLE 66R01P and SLE 66R01PN reads the Configuration

Byte and sets its internal states accordingly, see also the Figure 18. This information is not updated until the next

execution of REQA or WUPA commands in IDLE or HALT state even when the CONFIG byte is changed in the

EEPROM.

Frame Delay Time

For information about Frame Delay Time (FDT), please refer to ISO/IEC 14443-3 Type A Specification.

Generally the FDT is measured between the last rising edge of the pause transmitted by the PCD and the falling

edge of the first load modulation within the start bit transmitted by the my-d™ move and my-d™ move NFC. If

more then one ISO/IEC 14443-3 Type A compatible chip is in the operating field of the reader all of them must

respond in a synchronous way which is needed for the anticollision procedure.

For detailed timings see Table 1 of ISO/IEC 14443-3 Type A Specification.
