xD-PICTURE CARD INTERFACE
MEMORY STICK INTERFACE
DESCRIPTION
This general purpose pin may be used either as input, edge sensitive
interrupt input, or output. Custom firmware is required to activate this
function.
Secure Digital Write Protected GPIO
This is a GPIO designated by the default firmware as the Secure
Digital card interface mechanical write protect detect pin.
Memory Stick Bus State
This pin is connected to the bus state pin of the MS device. It is used
to control the Bus States 0, 1, 2, and 3 (BS0, BS1, and BS3) of the
MS device.
This general purpose pin may be used either as input, edge sensitive
interrupt input, or output. Custom firmware is required to activate this
function.
Memory Stick Card Insertion GPIO
This is a GPIO designated by the default software as the Memory
Stick card detection pin and has a weak internal pull-up resistor.
Memory Stick System Clock
This pin is an output clock signal to the MS device.
Memory Stick System Data In/Out
These pins are the bi-directional data signals for the MS device. In
serial mode, the most significant bit (MSB) of each byte is
transmitted first by either the memory stick controller MSC or the MS
device on MS_D0.
MS_D0, MS_D2, and MS_D3 have weak pull-down resistors. MS_D1
has a pull-down resistor if it is in parallel mode. Otherwise, it is
disabled. In 4- or 8-bit parallel modes, all MS_D7 - MS_D0 signals
have weak pull-down resistors.
xD-Picture Card Data 7-0
These pins are the bi-directional data signals xD_D7 - xD_D0 and
have weak internal pull-down resistors.
xD-Picture Card Address Strobe
This pin is an active high Address Latch Enable (ALE) signal for the
xD-Picture Card device. This pin has a weak pull-down resistor that
is permanently enabled.
