Note: IDE_DATA[15:0] and IDE_IRDY[0:1] (DSTROBE[0:1]) signals are shown at both the host and the device to empha-
size that cable settling time and cable propagation delay do not allow the data signals to be considered stable at the
host until a certain amount of time after they are driven by the device.
