Notes-

1. t

is minimum total cycle, t

is minimum DIOR-/DIOW- assertion time, and t

is the minimum

DIOR-/DIOW- negation time. A host implementation shall lengthen t

to ensure that t

is equal to or

greater than the value reported in the devices IDENTIFY DEVICE data. A device implementation

shall support any length host implementation.

2. This parameter specifies the time from the negation edge of DIOR- to the time that the data is

released by the device.

3. The delay from the activation of FIOR- or DIOW- until the state of IORDY is first sampled. If

IORDY is inactive then the host shall wait until IORDY is active before the PIO cycle is complete. If

the device is not driving IORDY negated at the t

after the activation of DIOR-

or DIOW-, that t

shall be met and t

is not applicable. If the device is driving IORDY
