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.
The signal should be grounded by the host.
The signal should be tied to VCC by the host.
The mode is required for CompactFlash TM Storage Cards.
The – CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled up on 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.
If DMA operations are not used, the signal must be held high or tied to VCC by the host, also for read
registers.
Signal usage in True IDE Mode except when Ultra DMA mode protocol is active.
Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active.
Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Read is active. The signal should be
grounded by the host.
In PC-Card mode, the IOIS16 signal does not work as fully specified. If a host uses this signal, this may
result in 16 bit accesses being changed to two 8 bit accesses. Depending on the address, this may result
in an incompatibility with the host controller.
In PC-Card mode (memory and I/O), 16 bit ATA register file accesses (i.e. both -CE1 and -CE2 asserted) do
not work as fully specified if A0 is high.
If you have host-card incompatibilities please contact Swissbit.
