Command
In the inquiry/selection host command wait state, send selection commands from the host in the order of device selection,
clock mode selection, and new bit rate selection to set up the RX610 according to the responses to inquiry commands.
Note that the supported device inquiry and clock mode inquiry commands are the only inquiry commands that can be
sent before the clock mode selection command; other inquiry commands must not be issued before the clock mode
selection command. If commands are issued in an incorrect order, the RX610 returns a response indicating a command
error. Figure 26.29 shows an example of the procedure to use inquiry/selection host commands.
