|
| The Input Acknowledge signal is asserted by the CompactFlash Storage Card | |||
(PC Card I/O Mode) |
|
|
| when the card is selected and responding to an I/O read cycle at the address | ||
Input Acknowledge |
|
|
| that is on the address bus. This signal is used by the host to control the enable of | ||
|
|
|
|
| ||
|
|
|
|
| any input data buffers between the CompactFlash Storage Card and the CPU. | |
DMARQ |
|
|
| This signal is a DMA Request that is used for DMA data transfers between host | ||
|
|
|
|
| ||
(True IDE Mode) |
|
|
| and device. It shall be asserted by the device when it is ready to transfer data to | ||
|
|
|
|
| or from the host. For Multiword DMA transfers, the direction of data transfer is | |
|
|
|
|
| controlled by | |
|
|
|
|
| ||
|
|
|
|
| negating DMARQ, and reasserting DMARQ if there is more data to transfer. | |
|
|
|
|
| DMARQ shall not be driven when the device is not selected. | |
|
|
|
|
| While a DMA operation is in progress, | |
|
|
|
|
| and the width of the transfers shall be 16 bits. | |
|
|
|
|
| If there is no hardware support for DMA mode in the host, this output signal is not | |
|
|
|
|
| used and should not be connected at the host. In this case, the BIOS must report | |
|
|
|
|
| that DMA mode is not supported by the host so that device drivers will not | |
|
|
|
|
| attempt DMA mode. | |
|
|
|
|
| A host that does not support DMA mode and implements both PCMCIA and | |
|
|
|
