6.3.2.5. SD/MMC Controller

The sdmmc_l3master register in the system manager controls the HPROT and HAUSER fields of the SD/MMC master port.

Note: Register bits should be accessed only when the master interface is guaranteed to be in an inactive state.

You can program software to select the clock’s phase shift for cclk_in_drv and cclk_in_sample by setting the drive clock phase shift select (drvsel) and sample clock phase shift select (smplsel) bits of the sdmmc register in the system manager.
