Description
RDY/-BSY
(PC Card Memory Mode)
O
37
In Memory Mode this signal is set high when the
CompactFlash
TM
Storage Card is ready to accept a new
data transfer operation and held low when the card is
busy. The Host memory card socket must provide a
pull-up resistor. At power up and at Reset, the
RDY/-BSY is held low (busy) until the CompactFlash
TM
Storage Card has completed its power up or reset
function. No access of any type should be made to the
CompactFlash
TM
Storage Card during this time. The
RDY/-BSY signal is held high (disabled from being busy)
whenever the following condition is true: The
CompactFlash
TM
Storage Card has been powered up with
+RESET continuously disconnected or asserted.
-IREQ
(PC Card I/O Mode)
I/O Operation- After the CompactFlash
TM
Storage has
been configured for I/O operation, this signal is used
as –Interrupt Request. This line is strobed low to
generate a pulse mode interrupt or held low for a level
mode interrupt.
INTRQ
(True IDE Mode)
In True IDE Mode signal is an active high Interrupt
Request to the host.
A[10:0]
(PC Card Memory Mode)
I
8, 10,
11, 12,
14, 15,
16, 17,
18, 19,
20
These address lines along with the –REG signal are used
to select the following: The I/O port address registers
within the CompactFlash
TM
Storage Card, the memory
mapped port address registers within the
CompactFlash
TM
Storage Card, a byte in the card’s
information structure and its configuration control and
status registers.
A[10:0]
(PC Card I/O Mode)
The signal is the same as the PC Card Memory Mode
signal.
A[2:0]
(True IDE Mode)
In True IDE Mode only HA[2:0] are used to select the one
of eight registers in the Task File, the remaining address
lines should be grounded by the host .
-CE1,-CE2
(PC Card Memory Mode)
Card Enable
I
7, 32
These input signals are used 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 the A0 and –CE2. A
multi-plexing scheme based on A0, -CE1, -CE2 allows 8
bit hosts to access all data on D0-D7.
-CE1,-CE2
(PC Card I/O Mode)
Card Enable
This signal is the same as the PC Card Memory Mode
signal.
-CS0,-CS1
(True IDE Mode)
In the True IDE Mode CS0 is the chip select for the task
file registers while CS2 is used to select the Alternate
Status Register and the Device Control Register.
-CSEL
(PC Card Memory Mode)
I
39
This signal is not used for this mode.
-CSEL
(PC Card I/O Mode)
This signal is not used for this mode.
-CSEL
(True IDE Mode)
This internally pulled up signal is used to configure this
device as a Master or a Slave when configured in the
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.
