Number
Description
BVD2
(PC Card Memory Mode)
I/O
45
This output line is always driven to a high state in Memory
Mode since a battery is not required for this product.
-SPKR
(PC Card I/O Mode)
This output line is always driven to a high state in I/O Mode
since this product produces no audio.
-DASP
(TrueIDE Mode)
In the TrueIDE Mode, this input/output is the Disk
Active/Slave Present signal in the Master/Slave handshake
protocol.
-CD1, -CD2
(PC Card Memory Mode)
I/O
26, 25
These Card Detect pins are connected to ground on the card.
They are used by the host to determine that the card is fully
inserted into the socket.
-CD1, -CD2
(PC Card I/O Mode)
This signal is the same as Memory Mode.
-CD1, -CD2
(TrueIDE Mode)
These signals are not used in TrueIDE Mode.
D15 - D00
(PC Card Memory Mode)
I/O
31, 30,
29, 28,
27, 49,
48, 47, 6,
5, 4, 3, 2,
23, 22, 21
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
PC Card I/O Mode
This signal is the same as the PC Card Memory Mode signal.
D15 - D00
(TrueIDE Mode)
In TrueIDE Mode, all Task File operations occur in byte mode
on the low order bus D00-D07 while all data transfers are 16
bit using D00-D15.
-IOWR
(PC Card Memory Mode
except UDMA protocol
active)
STOP
(All Modes: UDMA protocol
active)
I
35
This signal is not used in this mode.
In all modes, while UDMA mode protocol is active, the
assertion of this signal causes the termination of the UDMA
data burst.
-IOWR
(PC Card I/O Mode except
UDMA protocol active)
STOP
(All Modes: UDMA protocol
active)
The I/O Write strobe pulse is used to clock I/O data onto the
data bus and into the controller registers. The clocking
occurs on the negative to positive edge of the signal (trailing
edge).
Same as STOP above.
-IOWR
(TrueIDE Mode except
UDMA protocol active)
STOP
(All Modes: UDMA protocol
active)
In TrueIDE Mode, this signal has the same function as in PC
Card I/O Mode.
Same as STOP above.
