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.

Function Code
: 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
IDE Mode. To configure the card in True IDE Mode, the 50-pin
socket must be power cycled with the card inserted and -OE (output
enable) grounded by the host.
