Table 185. IDE PIO and Multiword DMA ModeTiming
82801EB ICH5 / 82801ER ICH5R 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
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
