Depending on a type of command and the communication designation, receiving the command from a host device to the controller and
the response to the host device vary.
(1) No response
When the controller receives a reset command, the controller does not send any response, performs resetting and waits for a command.
(2) Single response
When single trigger (ST/st), single auto (SA/sa), single input trigger (SI), polling auto (PA/pa) or polling input trigger (PI) is specified
by a command to communicate with the tag, or when a command not for the communication with the tag (communication subcommand,
controller control command or host command) is specified, one response is returned to one command.
(3) Several responses
When repeat auto (RA) or repeat input trigger (RI) is specified by a command to communicate with the tag, several responses are sent to
one command.
