The CompactFlash Storage Card and CF+ 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 and CF+ 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.
