Enhanced Secure Digital Host Controller
20.4.1
The DMA system address register contains the lower 32-bits of the system memory address used for DMA
transfers. Only access this register when no transactions are executing (after transactions have stopped).
The host driver should wait until PRSSTAT[DLA] is cleared.
20.4.2
The block attributes register configures the number of data blocks and the number of bytes in each block.
Only access this register when no transactions are executing (after transactions have stopped). The host
driver should wait until PRSSTAT[DLA] is cleared. During a data transfer,

DMA System Address Register (DSADDR)
Block Attributes Register (BLKATTR)
DMA system address, lower 32 bits. When the eSDHC stops a DMA transfer, this register points to the system
address of the next contiguous data position. The upper four bits of the DMA system address are stored in
ECMCR[ESDHC_UPRADR], see
Note: The DS_ADDR must be aligned to a four-byte boundary; the two least-significant bits must be cleared.

This register contains only the lower 32 bits of the DMA address. The 4
high-order bits are in ECMCR[ESDHC_UPRADR]; see
