The registers in this section are associated with the system. This includes the DMA AXI interface and various clock and reset signals. All registers are 32 bits wide.
The resets and reference clock register controls are in the CRP
register set that is located at base address 0xF126_0000.
Note: The interrupts are included in the Interrupt and Status Registers section.

| SD_eMMC 0 | SD_eMMC 1 | ||
| Reference Clock Controls in the CRP register module | |||
| SD0_REF_CTRL | SD1_REF_CTRL | RW | SD_eMMC reference clock for DIV_CLK module. |
| SDIO_DLL_REF_CTRL | RW | Program DLL reference clock frequency for both SD DLL modules. Write protected. | |
| RST_SDIO0 | RST_SDIO1 | RW | Controller is also reset when the PMC is reset. Device-level resets are included in the Resets Overview section. |
