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.
