Register : Data FIFO Access - data

Description

Provides read/write access to data FIFO. Addresses 0x200 and above are mapped to the data FIFO. More than one address is mapped to data FIFO so that FIFO can be accessed using bursts.

Data Structure Documentation

struct ALT_SDMMC_DATA_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.
