IDE_DATA[15:0] (device)

Notes:

1)The host can assert IDE_IOW[0:1]# (STOP[0:1]#) to request termination of the UltraDMA burst no sooner than tRP after IDE_IOR[0:1]# (HDMARDY[0:1]#) is de-asserted.

2)If the tSR timing is not satisfied, the host may receive up to two additional data WORDs from the device.
