1. Loading capacitor condition is less than or equal to 30pF.
2. An external resistor (100 ~ 200 ohm) should be inserted in series to provide current control on the
MS_SDIO pin, because of a possibility of signal conflict between the MS_SDIO pin and Memory Stick
SDIO pin when the pin direction changes.
3. If the MSC2[RED] bit = 0, MSHC samples MS_SDIO input data at MS_SCLKO rising edge.
4. If the MSC2[RED] bit = 1, MSHC samples MS_SDIO input data at MS_SCLKO falling edge.
