(4) Clock Mode Selection
In response to a clock mode selection command sent from the host, the RX610 checks if the selected clock mode is
supported. When the selected mode is supported, the RX610 specifies this clock mode for use and returns a response
(06h). If the selected mode is not supported or the sent command is illegal, the RX610 returns an error response (91h).
Be sure to issue a clock mode selection command only after issuing a device selection command. Even when 00h or 01h
has been returned as the number of supported clock modes in response to a clock mode inquiry command, issue a clock
mode selection command to specify the clock mode that has been returned as the result of the inquiry.
