Hi Feiyun,

If MMCSD is enabled in sysconfig, and the proper clock source is selected in sysconfig/mmcsd pane, the code is generated for configuring the MMCSD clock.

Can the CLK be kept in the ON state? Now, the CLK output is only available when sending commands.

Hi Feiyun,

You can set the MMC clock free running: CLKEXTFREE bit of MMC_CON Register.
