| 31:30 | EXT_CLK_MUX_CTRL |
Input clock control for cclk_in. The MUX controlled by these bits exists outside DWC_mobile_storage IP. |
RW | 0x0 | ||||||
| 29:23 | CLK_DRV_PHASE_CTRL |
Control for amount of phase shift on cclk_in_drv clock. Can choose three MSBs to control delay lines and four LSBs to control phase shift; alternatively, use only LSBs. |
RW | 0x0 | ||||||
| 22:16 | CLK_SMPL_PHASE_CTRL |
Control for amount of phase shift on cclk_in_sample clock. Can choose three MSBs to control delay lines and four LSBs to control phase shift; alternatively, use only LSBs. |

| 15 | MMC_VOLT_REG_15 |
Support for 1.2V. MMC_VOLT_REG bits; must be read in combination with UHS_VOLT_REG to decode output selected voltage. The biu_volt_reg_1_2[NUM_CARD_BUS-1:0] signal decodes the voltage combination selected for the I/O voltage logic. Host controllers that support only SD standard or standard versions before eMMC4.41 do not program MMC_VOLT_REG. Only host controllers that support all three versions3.3,1.8,1.2 Vcan program MMC_VOLT_REG and connect biu_volt_reg_1_2.
