266X CompactFlash Card
Transcend Information Inc.
5
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 optional for CF+ Cards, but 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.
