-SPKR
(PC Card I/O
mode) This line is the Binary Audio output
from the card. If the Card does not
support the Binary Audio function, this
line should be held negated.
-DASP
(True IDE mode) In the true IDE mode, this input/output
is the Disk Active/Slave Present
signal in the Master/Slave handshake
protocol.
-CD1, -CD2
(PC Card memory
mode) 26, 25 O These Card Detect pins are
connected to ground on the
SiliconDrive CF, and are used by the
host to determine that the SiliconDrive
CF is fully inserted into its socket.
-CD1, -CD2
(PC Card I/O
Mode) This signal is the same for all modes.
-CD1, -CD2
(True IDE mode) This signal is the same for all modes.
-CE1, -CE2
(PC Card memory
mode)
Card Enable 7, 32 I 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, and -CE2 allows 8-bit hosts to
access all data on D0-D7. See
