Signal name
Direction Pin No.
Description
RESET
(PC Card Memory mode)
I
58
This signal is active high RESET pin. If this signal is
asserted high, the card internal initialization begins to
operate. During the card internal initialization
RDY/-BSY is low. After the card internal initialization
RDY/-BSY is high.
RESET
(PC Card I/O mode)
This signal is active high RESET pin. If this signal is
asserted high, the card internal initialization begins to
operate. In this mode, RDY/-BSY signal can not be
used, so using Status Register the Ready/Busy status
can be confirmed.
-RESET
(True IDE mode)
This signal is active low -RESET pin. If this signal is
asserted low, all the register’s in this card are reset.
In this mode, RDY/-BSY signal can not be used, so
using status register the Ready/Busy status can be
confirmed.
VCC
(PC Card Memory mode)
—
17, 51
+5 V, +3.3 V power.
VCC
(PC Card I/O mode)
VCC
(True IDE mode)
-VS1, -VS2
(PC Card Memory mode)
O
43, 57
These signals are intended to notify VCC requirement
to host. -VS1 is held grounded and -VS2 is
nonconnected in this card.
-VS1, -VS2
(PC Card I/O mode)
-VS1, -VS2
(True IDE mode)
-WAIT
(PC Card Memory mode)
O
59
This signal is active low -WAIT pin. In this card this
signal is constantly high level.
-WAIT
(PC Card I/O mode)
IORDY
(True IDE mode)
This output signal may be used as IORDY. In this
card this signal is constantly high impedance.
-WE
(PC Card Memory mode)
I
15
-WE is used for the control of writing register’s data in
attribute memory area or task file area.
-WE
(PC Card I/O mode)
-WE is used for the control of writing register’s data in
attribute memory area.
-WE
(True IDE mode)
This input signal is not used and should be connected
to VCC by the host.
