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
clocks when the drive mode is Mode 2 or greater. Refer to the ISP field in the IDE Timing Register
3. PIORDY sample point from DIOx# assertion, PDIOx# active pulse width and PDIOx# inactive pulse width
cycle time is the compatible timing when the drive mode is Mode 0/1. Refer to the TIM0/1 field in the IDE
timing register.
4. PDIOx# inactive pulse width is programmable from 1-4 PCI clocks when the drive mode is Mode 2 or
greater. Refer to the RCT field in the IDE Timing Register.
