Signal name
Direction Pin No.
Description
-OE
(PC Card Memory mode)
I
1
-OE is used for the control of reading register’s data in
attribute area or task file area.
-OE
(PC Card I/O mode)
-OE is used for the control of reading register’s data in
attribute area.
-ATASEL
(True IDE mode)
To enable True IDE mode this input should be
grounded by the host.
RDY/-BSY
(PC Card Memory mode)
O
113
The signal is RDY/-BSY pin. RDY/-BSY pin turns low
level during the card internal initialization operation at
VCC applied or reset applied, so next access to the
card should be after the signal turned high level.
-IREQ
(PC Card I/O mode)
This signal is active low -IREQ pin. The signal of low
level indicates that the card is requesting software
service to host, and high level indicates that the card
is not requesting.
INTRQ
(True IDE mode)
This signal is the active high Interrupt Request to the
host.
-REG
(PC Card Memory mode)
Attribute memory select
I
99
-REG is used during memory cycles to distinguish
between task file and attribute memory accesses.
High for task file, Low for attribute memory is
accessed.
-REG
(PC Card I/O mode)
-REG is constantly low when task file or attribute
memory is accessed.
-REG
(True IDE mode)
This input signal is not used and should be connected
to VCC.
RESET
(PC Card Memory mode)
I
105
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.
