Table 1-2.
Parameter
Error detection forward
link
Error detection return link
Error code during return
link
Error coding if forward
CRC was correct but
command unknown
Error coding if memory
address is unknown but
command was known.
Error coding if program
procedure is failed
Address overflow during
deterministic arbitration
Error Detection and Signalling
Description
Header plausibility check
2-bit CRC for command frame
16-bit CRC over the whole frame
Bit length check
Loop function for CRC
Once received, a decoded bit is
backscattered in full duplex mode
16-bit CRC
CRC length is adaptive, also in loop
mode
Inside the 8-bit status2 transfer
Disabling full duplex in the forward
direction and sub-carrier (OSC / 4)
during the first symbol after EOF1
Sub-carrier modulation (OSC / 4)
during the first header symbol of the
return link
Sub-carrier: OSC / 8
Sub-carrier modulation OSC / 4
Comment
To be synchronized to the reader, the
header_ok check and the command CRC
have to be received successfully; then
the tag can communicate with the reader
Data CRC wrong
Bit length coding wrong
Page locked (for programming)
No error code (status2) is backscattered
Tag is silent during return link, and
becomes asynchronous to the reader
No error code (status2) is backscattered
Tag is silent during the rest of the return
link
Sub-carrier modulation is active until the
return link header
Sub-carrier is active if the arbitration was
started and the arbitration pointer (one bit
before the contents is backscattered) is
outside the memory
