6.9.5.19.2 MMC1/2 - SD/SDIO Interface

MMC1 and MMC2 interfaces are compliant with the SD Host Controller Standard Specification 4.10 and SD

Physical Layer Specification v3.01 as well as SDIO Specification v3.00 and they support the following SD Card

applications:

• Default speed

• High speed

• UHS–I SDR12

• UHS–I SDR25

• UHS–I SDR50

• UHS–I SDR104

• UHS–I DDR50

Table 6-86 presents the required DLL software configuration settings for MMC1 timing modes.
