Each MMCSD Host Controller supports:
- Integrated DMA controller
supporting SD Advanced DMA - ADMA2 and ADMA3 (for more information about
ADMA support, see Section 12.4.5.4.4, Advanced DMA)
- System Bus Interface:
- 64-bit data width
(host
interface)
- 64-bit address
- Clock asynchronous to
MMCSD clock (MMCi_CLK)
- Little endian
only
- Configuration Bus Interface:
- 32-bit data width
(target
interface)
- Linear incrementing
addressing mode
- 32-bit aligned
accesses only
- Little endian
only
- Muxing of other LVCMOS
interfaces onto the MMCSD interface at the SoC level (See the device
specific datasheet for supported interfaces, if applicable)
