Signal Name
-CE1, -CE2

Pin
Description
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.

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.
-CS0, -CS1
(True IDE Mode)
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.
(PC Card Memory Mode)
-CSEL
This signal is not used for this mode, but should be connected by the host to PC
Card A25 or grounded by the host.
(PC Card I/O Mode)
-CSEL
This internally pulled up signal is used to configure this device as a Master or a
Slave when configured in the True IDE Mode.
(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.

I/O
These lines carry the Data, Commands and Status information between the host
and the controller. D00 is the LSB of the Even Byte of the Word. D08 is the LSB
of the Odd Byte of the Word.

D15 - D00
(True IDE Mode)
In True IDE Mode, all Task File operations occur in byte mode on the low order
bus D[7:0] while all data transfers are 16 bit using D[15:0].
