266X CompactFlash Card

True IDE Mode I/O Transfer Function

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.

Table: True IDE Mode I/O Function defines the function of the operations for the True IDE Mode.
