DESCRIPTION
CF Hardware

CF IO Read
CF_nRESET
This pin is an active low hardware reset signal to CF
device.
This pin is an active low read strobe signal for CF device,
when the CFC is enabled.
This pin is an active low write strobe signal for CF device,
when the CFC is enabled.
SmartMedia INTERFACE
O8
This pin is an active low write protect signal for the SM
device, when the SMC is enabled.
O8
This pin is an active high Address Latch Enable signal for
the SM device, when the SMC is enabled.
O8
This pin is an active high Command Latch Enable signal
for the SM device, when the SMC is enabled.
I/O8
These pins are the bi-directional data signal SM_D7-
SM_D0, when the SMC is enabled.
O8
This pin is an active low read strobe signal for SM device,
when SMC is enabled.
O8
This pin is an active low write strobe signal for SM device,
when SMC is enabled.
IPU
A write-protect seal is detected, when this pin is low.

I
This pin is connected to the BSY/RDY pin of the SM
device.
An external pull-up resistor is required on this signal. The
pull-up resistor should be attached to the power of
SM/NAND flash device.
This pin is the active low chip enable signal to the SM
device.
This is the card detection signal from SM device to
indicate if the device is inserted.
MEMORY STICK INTERFACE
O8
This pin is connected to the BS pin of the MS device.
It is used to control the Bus States 0, 1, 2 and 3 (BS0,
BS1, BS2 and BS3) of the MS device.
I/O8
This pin is a bi-directional data signal for the MS device.
Most significant bit (MSB) of each byte is transmitted first
by either MSC or MS device.
The bi-directional data signal has an internal weak pull-
down resistor.
IO8PD
This pin is a bi-directional data signal for the MS device.
The bi-directional data signal has an internal weak pull-
down resistor that is internally controlled.
I/O8
This pin is a bi-directional data signal for the MS device.
The bi-directional data signal has an internal weak pull-
down resistor.
IPU
This pin is the card detection signal from the MS device to
indicate, if the device is inserted.
