CompactFlash Memory Card Interface Description
1. t
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 t
cycle time requirements are greater than the sum of t
or both t
A device implementation shall support any legal host implementation.
2. This parameter specifies the time from the negation edge of /IORD to the time that the data bus is no longer
driven by the device (tri-state).
3. SanDisk CompactFlash Memory Cards do not assert an -IORDY signal.
3.4. Card Configuration
The CompactFlash Memory Cards are identified by appropriate information in the Card Information Structure (CIS).
The following configuration registers are used to coordinate the I/O spaces and the Interrupt level of cards that are
located in the system. In addition, these registers provide a method for accessing status information about the
CompactFlash Card that may be used to arbitrate between multiple interrupt sources on the same interrupt level or to
replace status information that appears on dedicated pins in memory cards that have alternate use in I/O cards.
