Figure 27-51 shows the DLL tuning procedure when SDR104 and HS200 modes are used.
The BRR interrupt has to be enabled during tuning for functionality to succeed. The other error flags in MMCHS_IE can also be enabled for debug purposes. The MMCHS_SYSCTL[25] SRC bit can be set for command related interrupts, but caution has to be taken such that the MMCHS_SYSCTL[26] SRD bit is not set even when DAT related errors occurred, until after tuning completion.
