Note:

IDE_DATA[15:0] and IDE_IOR[0:1]# (HSTROBE[0:1]#) signals are shown at both the device and the host to
emphasize that cable settling time and cable propagation delay do not allow the data signals to be considered sta-
ble at the device until a certain amount of time after they are driven by the device.
