If the EAS bit is set to 0 the I

3.5 Error handling

3.5.1 TRANSMISSION ERRORS

According to ISO/IEC 15693 the Label IC will not respond if a transmission error (CRC, bitcoding, bitcount,

wrong framing) is detected and will silently wait for the next correct received command.

3.5.2 NOT SUPPORTED COMMANDS OR OPTIONS

If the received command or option is not supported, the behaviour of the Label IC is depending of the

addressing mechanism.

3.5.2.1 Non Addressed Mode

The label IC remains silent.

3.5.2.2 Addressed or Selected Mode

The addressed or selected label IC responds with the error code “0F” hex (error with no information given or

error code is not supported).

If the Inventory flag or the protocol extension flag is set the label IC will not respond if the command or option

is not supported.

3.5.3 PARAMETER OUT OF RANGE

3.5.3.1 Read commands

If the sum of the first block number and the number of blocks exceeds the total available number of user

blocks, the number of transmitted blocks is less than the requested number of blocks, which means that the

last returned block is the highest available user block, followed by the 16 bit CRC and the EOF.
