True IDE Mode I/O Transfer Function

The CompactFlash Storage Card can be configured in a True IDE Mode of operation. The CompactFlash Storage
Card is configured in this mode only when the -OE input signal is grounded by the host during the power off to
power on cycle. Optionally, CompactFlash Storage Cards may support the following optional detection methods:
1. The card is permitted to monitor the –OE (-ATA SEL) signal at any time(s) and switch to PCMCIA mode upon
detecting a high level on the pin.
2. The card is permitted to re-arbitrate the interface mode determination following a transition of the (-)RESET pin.
3. The card is permitted to monitor the –OE (-ATA SEL) signal at any time(s) and switch to True IDE mode upon
detection of a continuous low level on pin for an extended period of time.
Table: True IDE Mode I/O Function defines the function of the operations for the True IDE Mode.
