O8
MS Bus State:
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.
MS_SDIO/MS_

I/O8PD
MS System Data In/Out:
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.
MS_D1
20
I/O8PD
MS System Data In/Out:
This pin is a bi-directional data signal for the MS device.
This pin has internally controlled weak pull-up and pull-down
resistors for various operational modes.
MS_D[3:2]
22
21
I/O8PD
MS System Data In/Out:
This pin is a bi-directional data signal for the MS device.
The bi-directional data signal has an internal weak pull-down
resistor.
MS_INS

IPU
MS Card Insertion:
This pin is the card detection signal from the MS device to
indicate, if the device is inserted.
This pin has an internally controlled weak pull-up resistor.
MS_SCLK
23
O8
MS System CLK:
This pin is an output clock signal to the MS device.
The clock frequency is software configurable.
