Iso14b.Halt
Switch the PICC with the given PUPI serial number into halt state, so that it will not answer to further Iso14b.Request commands, except when the ReqAll flag parameter of the Iso14b.Request command is set. The memory occupied by this PICC's information will also be freed, which makes it is available for future calls of the Iso14b.Request command. Use this command in order to deactivate some of the PICCs in case the Iso14b.ErrMem status code has been returned by the last call of Iso14b.Request.
This command only works for PICCs in ready state. For PICCs in active state, the Iso14L4.Deselect command should be used instead.
