Command interface
There are two types of bus cycles and timing sequences that occur in the PCMCIA type
interface, direct mapped I/O transfer and memory access. Three types of bus cycles are
also available in true IDE interface type: PIO transfer, multi-word DMA transfer and Ultra
DMA transfer.
Refer to CF specification 3.0 for details about read and write timing parameters and relative
timing diagrams.
In order to set the card mode, the -OE (-ATASEL) signal must be set and kept stable before
applying V
mode, -OE(-ATASEL) must be driven High, while it must be driven Low to place the card in
true IDE mode.
