■ Communications with the Host Device
Communicate with the host device only after confirming that the CIDRW Controller has started. Also,
unstable signals may occur at the host interface when the CIDRW Controller is started. When initializ-
ing operation, clear the reception buffer at the host device or take other suitable methods to clear
unwanted signals.
■ Startup Precaution
Never turn OFF the power supply while the CIDRW Controller is starting, including when power is
turned ON, when the mode is changed, or when the CIDRW Controller is being reset. Doing so may
damage the CIDRW Controller.
