These Card Detect pins are connected to ground on the CompactFlash Storage

Card. They are used by the host to determine that the CompactFlash Storage

Card is fully inserted into its socket.

This signal is the same for all modes.

These input signals are used both to select the card and to indicate to the card

whether a byte or a word operation is being performed. -CE2 always accesses

the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the

word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1,

-CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29,

Table 31, Table 35, Table 36 and Table 37.

This signal is the same as the PC Card Memory Mode signal.

In the True IDE Mode, -CS0 is the address range select for the task file

registers while -CS1 is used to select the Alternate Status Register and the

Device Control Register.

While –DMACK is asserted, -CS0 and –CS1 shall be held negated and the

width of the transfers shall be 16 bits.

This signal is not used for this mode, but should be connected by the host to PC

Card A25 or grounded by the host.

This signal is not used for this mode, but should be connected by the host to PC

Card A25 or grounded by the host.

This internally pulled up signal is used to configure this device as a Master or a

Slave when configured in the True IDE Mode.

When this pin is grounded, this device is configured as a Master.

When the pin is open, this device is configured as a Slave.
