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.
Note: The interrupts are included in the Interrupt and Status Registers section.
Register Name | Access Type | Description | |
---|---|---|---|
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. |
