The PWM can be programmed to select one of two clock signals as its source frequency. The selected
clock signal is passed through a divider and a prescaler before being input to the counter. The output is
available at the pulse-width modulator output (PWMO) external pin. Its timing diagram is shown in

No.
Loading capacitor condition is less than or equal to 30pF.
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.
If the MSC2[RED] bit = 0, MSHC samples MS_SDIO input data at MS_SCLKO rising edge.
If the MSC2[RED] bit = 1, MSHC samples MS_SDIO input data at MS_SCLKO falling edge.
