The delay from DIOR# 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 can be
completed. If the device is not driving
IORDY negated at the time tA after the
activation of DIOR# or DIOW#, then t5
shall be met and tRD is not applicable. If
the device is driving IORDY negated at the
time tA after the activation of DIOR# or
DIOW#, then tRD shall be met and t5 is not
applicable.
