Appendix B: Register Details
Register (sdio) SDMA_system_address_register
Register SDMA_system_address_register Details
This register contains the system memory address for a DMA transfer. When the Host Controller (HC)
stops a DMA transfer, this register shall point to the system address of the next contiguous data position.
It can be accessed only if no transaction is executing (i.e. after a transaction has stopped). Read operations
during transfer return an invalid value. The Host Driver (HD) shall initialize this register before starting a
DMA transaction. After DMA has stopped, the next system address of the next contiguous data position
can be read from this register. The DMA transfer waits at every boundary specified by the Host DMA
