Device address consists of signals IDE_CS[0:1]# and IDE_ADDR[2:0].
Negation of IDE_IORDY0,1 is used to extend the PIO cycle. The determination of whether or not the cycle is to be
extended is made by the host after t
Device never negates IDE_IORDY[0:1]. Device keeps IDE_IORDY[0:1] released, and no wait is generated.
Device negates IDE_IORDY[0:1] before t
released, and no wait is generated.
Device negates IDE_IORDY[0:1] before t
more than 5 ns before release. A wait is generated.
The cycle completes after IDE_IORDY[0:1] is reasserted. For cycles where a wait is generated and IDE_IOR[0:1] is
asserted, the device places read data on IDE_DATA[15:0] for t
