This is an Output Enable strobe generated by the host interface. It is
used to read data from the CompactFlash Strage Card or CF+Card in
Memory Mode and to read the CIS and configuration registers.
In PC Card I/O Mode, this signal is used to read the CIS and configuration
registers.
To enable True IDE Mode this Input should be grounded by the host.
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.
CompactFlash Storage Card or CF+Card during this time.
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
–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.
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.
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.
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.
