To enable True IDE Mode this input should be grounded by the host.

(True IDE Mode)
O 37
In Memory Mode this signal is set high when the CompactFlash Storage
Card or CF+ 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 signal is held low(busy) until the
CompactFlash Storage Card or CF+ Card has completed its power up or reset
function. No access of any type should be made to the CompactFlash
Storage Card or CF+ Card during this time. The RDY/-BSY signal is held high
(disabled from being busy) whenever the following condition is true: The
CompactFlash Storage Card or CF+ Card has been powered up with +RESET
continuously disconnected or asserted.
I/O Operation – After the CompactFlash Storage Card or CF+ Card 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.
In True IDE Mode signal is the active high Interrupt Request to the host.

I 44
This signal is used during Memory Cycles to distinguish between
Common
Memory and Register (Attribute) Memory accesses.
High for Common
Memory, Low for Attribute Memory.
The signal must also be active (low) during I/O Cycles when the
I/O address
is on the Bus.
In True IDE Mode this input signal is not used and should be
connected to VCC by the host.

(True IDE Mode)
I 41
When the pin is high, this signal Resets the CompactFlash Storage Card or
CF+ Card. The CompactFlash Storage Card or
CF+ Card is Reset only at
power up if this pin is left high or open from power-
up. The CompactFlash
Storage Card or CF+ Card is
also Reset when the Soft Reset bit in the Card
Configuration Option Register is set.
This signal is the same as the PC Card Memory Mode signal.
In the True IDE Mode this input pin is the active low hardware
reset from the host.

(PC Card Memory Mode)
-VS1
-VS2
O 33,40
Voltage Sense Signals. -VS1 is grounded so that the
CompactFlash Storage
Card or CF+ Card CIS can be read at 3.3 volts and -
VS2 is reserved by
PCMCIA for a secondary voltage.
This signal is the same for all modes.
