3.24 ISO 15963 Transponder ‘General Protocol’ Command
This command allows to send any ISO 15693 general format protocol
command (flags field, command code field, parameters fields, application data
fields) to a ISO 15693 transponder and to receive, in case of successfull
operation, the response of the transponder (flag field, parameters fields, data
fields). For more details see the specific transponder data sheet and ISO 15693
protocol. If the ‘continous’ mode is enabled, it will be suspended by the
execution of this command and will be suspended as long as this command is
used; it will be resumed automatically when another type of command will be
executed.
