True IDE Mode I/O Transfer Function
This section contains valuable information on the True IDE Mode I/O Transfer function.
True IDE Mode I/O Function
SanDisk CompactFlash Memory cards can be configured in a True IDE Mode of operation.
Cards are configured in this mode only when the -OE input signal is grounded by the host
when power is applied to the cards. In this True IDE Mode, the PCMCIA protocol and
configuration are disabled and only I/O operations to the Task File and Data Register are
allowed. In this mode, no Memory or Attribute registers are accessible to the host.
CompactFlash cards permit 8-bit data accesses if the user issues a Set Feature Command to put
the device in 8-bit Mode.
Table 3-23 defines the function of the operations for the True IDE Mode.

: Removing and reinserting the card while the host computer's power
is on will reconfigure it to PC Card ATA mode from the original True

enable) grounded by the host.
