Error handling
Table 8-7.
If ATA5590 receives a command which is not known by the IC, the tag does not backscatter a
specific error code during the return link.
If the received invalid command is interpreted as a long command, the tag stops backscattering
the detected data during the forward link.
The following answers are backscattered by the tag:
• The command was known and the command CRC was correct: Normal operation
• The command was known but the CRC is wrong: The tag backscatters the error message
• The command is not known and the CRC is wrong: The tag backscatters the error message
• The command is not known but the CRC is correct:
(status2 register)
(status2 register)
Com(3:0)
– The tag backscatters a sub-carrier during the symbol after EOF1
– The tag stops backscattering the detected data (parameter field, address field, CRC
