Description

I/O WRITE:
This signal is not used in memory mode.The I/O write strobe
pulse is used to clock I/O data on the card data bus into the PC
Card controller registers when the PC Card is configured to use
the I/O interface.
The clocking will occur on the negative to positive edge of the
signal (trailing edge). In True IDE mode, this signal has the same
function as in PC Card I/O Mode
STATUS CHANGED:
This signal is asserted high as the BVD1 signal since a battery is
not used with this product.This signal is asserted low to alert the
host to changes in the RDY/-BSY and write protect states, while
the I/O interface is configured. Its use is controlled by the Card
config and status.
In the True IDE mode, this input / output is the pass diagnostic
signal in the Master/Slave handshake protocol.
CARD SELECT:
In True IDE mode, this signal is used for configure this device as
a master or slave. When it is grounded , the device is configured
as a master.
When this signal is open, the device is configured as a slave.
In I/O and memory mode, this signal is not used.
RESET:
When the pin is high, this signal resets the PC Card. The PC Card
is reset only at Power up if this pin is left high or open from power-
up. The PC Card is also reset when the soft reset bit in the Card
Configuration Option Register is set.
In the True IDE mode, this input pin is the active low hardware
reset from the host.
