These registers are present only in case of Scatter/Gather DMA. These registers are implemented in RAM instead of flop-based implementation. Holds the current buffer address. This register is updated as and when the data transfer for the corresponding end point is in progress. This register is present only in Scatter/Gather DMA mode. Otherwise this field is reserved.

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.
