MS System Data In/Out
These pins are the bi-directional data signals for the
MS device. MS_D0, MS_D2, and MS_D3 have weak
pull-down resistors.
In serial mode, the most significant bit (MSB) of each
byte is transmitted first by either MSC or MS device on
MS_D0.
In parallel mode, MS_D1 has a pull-down resistor,
otherwise it is disabled.
In 4- or 8-bit parallel mode, there is a weak pull-down
resistor on all MS_D7 - 0 signals.
MS_BS

O12
MS Bus State
This pin is connected to the bus state (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.
MS_SCLK

O12
MS System CLK
This pin is an output clock signal to the MS device.
The clock frequency is software configurable.

IPU
MS Card Insertion GPIO
This is a GPIO designated by the default firmware as
the Memory Stick card detection pin.

SD Clock
This is an output clock signal to SD/MMC device.
The clock frequency is software configurable.
SD_CMD

I/O12PU
SD Command
This is a bi-directional signal that connects to the CMD
signal of the SD/MMC device and has a weak internal
pull-up resistor.
