8.4 Error handling

8.4.1 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.

8.4.2 Not supported commands or options

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

depending on the addressing mechanism.

8.4.2.1 Non addressed mode

The label IC remains silent.

8.4.2.2 Addressed or selected mode

The addressed or selected label IC responds with the error code “0Fh” (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.

8.4.3 Parameter out of range

8.4.3.1 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.

8.4.3.2 Write and lock commands

If the address of a block to be written does not exist or a block to be written is locked the

behaviour of the Label IC is depending on the addressing mechanism.

8.4.3.3 Non addressed mode

The Label IC remains silent and aborts the command without writing anything.

8.4.3.4 Addressed or selected mode

The addressed or selected Label IC responds with the error code “0Fh” (error with no

information given or error code is not supported).
