Bits Access Reset Description
[31:0] RW 0x0 ALT_SDMMC_DBADDR_SDL

Field : sdl

Start of Descriptor List. Contains the base address of the First Descriptor.

The LSB bits [0/1/2:0] for 16/32/64-bit bus-width) are ignored and taken as all- zero by the IDMAC internally. Hence these LSB bits are read-only.

Data Structure Documentation

struct ALT_SDMMC_DBADDR_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
