Table 17-10. IDE PIO and Multiword DMA ModeTiming
82801DB ICH4 Datasheet
NOTES:
1. IORDY is internally synchronized. This timing is to guarantee recognition on the next clock.
2. PIORDY sample point from DIOx# assertion and PDIOx# active pulse width is programmable from 2–5 PCI
3. PIORDY sample point from DIOx# assertion, PDIOx# active pulse width and PDIOx# inactive pulse width
4. PDIOx# inactive pulse width is programmable from 1–4 PCI clocks when the drive mode is Mode 2 or greater.
