CompactFlash Memory Card Interface Description
3.7. True IDE Mode I/O Transfer Function
This section contains valuable information on the True IDE Mode I/O Transfer function.
3.7.1. True IDE Mode I/O Function
The CompactFlash Memory Card can be configured in a True IDE Mode of operation. This CompactFlash Card is
configured in this mode only when the -OE input signal is grounded by the host when power is applied to the card.
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.
NOTE: Removing and reinserting the CompactFlash Memory Card while the host computer’s power is on will
Table 3-25 defines the function of the operations for the True IDE Mode.
