Figure 3: PIO / Register Transfer to / from IDE device
Notes : Negation of IORDY by the drive is used to extend the PIO cycle. The determnation of whether the cycle is to be
extended is made by the host after tA fromthe Assertion of DIOR#or DIOW# The assertion and negation of IORDY are
described in the following three cases : -
1) Device never negates IORDY and no wait is generated.
2) Device negates IORDY before tA, but causes IORDY to be asserted before tA. IORDY is released prior to negation and
may be asserted for no more than 5ns before release : no wait generated.
3) Device negated IORDY before tA. IORDY is released prior to negation and may be asserted for no more than 5ns before
release : wait generated. The cycle completes after IORDY is reasserted. For cycles where a wait is generated and DIOR#
is asserted, the device shall place read data on DD[7:0] for tRD before asserting IORDY
