PIO Data Transfers
Figure 10 defines the relationships between the interface signals for PIO data
transfers. For PIO Modes 3 and above the minimum value of t
Word 68 in the IDENTIFY DEVICE parameter list. Table 22defines the
minimum value that will be placed in Word 68.
Notes: 1)
The PIO data transfer parameters are defined in Table 22: PIO Data Transfer
to/from Device.
Note: SanDisk CompactFlash Memory cards do not assert an -IORDY signal.

time, and t2i is the minimum command recovery time or command
inactive time. The actual cycle time equals the sum of the actual command
active time and the actual command inactive time. The three timing
requirements of t0, t2, and t2i shall be met. The minimum total cycle time
requirements are greater than the sum of t2 and t2i. This means a host
