AM3354: MMC0_CLK drive strength adjustment

Yume Lin

Prodigy 60 points

Part Number: AM3354

Hi,

We used MMC0 for SD slot in our design.

Per check datasheet, the drive strength of MMC0_CLK is 6mA.

Could it be adjusted to more than 6mA?

No.

The IOs used in AM335x do not have drive strength control. There is a slew rate bit, but this bit must remain in the default state of fast for the device to be compliant to timing parameters defined in the datasheet.
