Notes:

1)Device address consists of signals IDE_CS[0:1]# and IDE_ADDR[2:0].

2)Negation of IDE_IORDY[0:1] 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 tA from the assertion of IDE_IOR[0:1]# or IDE_IOW[0:1]#.

3)Device never negates IDE_IORDY[0:1]. Devices keep IDE_IORDY[0:1] released, and no wait is generated.

4)Device negates IDE_IORDY[0:1] before tA but causes IDE_IORDY[0:1] to be asserted before tA. IDE_IORDY[0:1] is released, and no wait is generated.

5)Device negates IDE_IORDY[0:1] before tA. IDE_IORDY[0:1] is released prior to negation and may be asserted for no more than 5 ns before release. A wait is generated.

6)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 tRD before asserting IDE_IORDY[0:1].
