ECC_startacc
These bits determine which byte of data/ecc to write to RAM.
| Module Instance | Base Address | Register Address |
|---|---|---|
| sdm_ecc_sdmmc_ecc_registerBlock | 0xFFA20000 | 0xFFA2007C |
Size: 32
Offset: 0x7C
Access: RW
Access mode: PRIVILEGEMODE
Note: The processor must make a privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
