133X CompactFlash Card

Transcend Information Inc.

Note: 1) These signals are required only for 16 bit accesses and not required when installed in 8 bit

systems. Devices should allow for 3-state signals not to consume current.

2) The signal should be grounded by the host.

3) The signal should be tied to VCC by the host.

4) The mode is required for CompactFlash Storage Cards.

5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not

pulled upon the card in these modes, it should not be left floating by the host in PC Card

modes. In these modes, the pin should be connected by the host to PC Card A25 or

grounded by the host.

6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For

proper operation in older hosts: while DMA operations are not active, the card shall ignore

this signal,including a floating condition

7) Signal usage in True IDE Mode except when Ultra DMA mode protocol is active.

8) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active.

9) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Read is active.

10) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Write is active.

11) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Read is active.

12) Signal usage in PC Card I/O and Memory Mode when Ultra DMA protocol is active.
