The SDMMC_IDMABASE0R register contains the memory buffer base address in single buffer configuration and the buffer 0 base address in double buffer configuration.
IDMABASE0 | Buffer 0 memory base address bits [31:2], shall be word aligned (bit [1:0] are always 0 and read only). This register can be written by firmware when DPSM is inactive (DPSMACT = 0), and can dynamically be written by firmware when DPSM active (DPSMACT = 1) and memory buffer 0 is inactive (IDMABACT = 1). |
