brp_Iso14b_Halt()

brp_errcode brp_Iso14b_Halt	(	brp_protocol	protocol,
		brp_buf	PUPI
	)

Switch the PICC with the given PUPI serial number into halt state, so that it will not answer to further brp_Iso14b_Request() commands, except when the ReqAll flag parameter of the brp_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 brp_Iso14b_Request() command. Use this command in order to deactivate some of the PICCs in case the BRP_Iso14b_ErrMem status code has been returned by the last call of brp_Iso14b_Request().

This command only works for PICCs in ready state. For PICCs in active state, the brp_Iso14L4_Deselect() command should be used instead.

Parameters

[in]	protocol	used to execute the command
[in]	PUPI	Pseudo-Unique PICC Identifier (PUPI) of the tag that should go into halt mode.
