Each MMCSD Host Controller supports:
- Integrated DMA controller supporting SD Advanced
DMA - ADMA2 and ADMA3 (for more information about ADMA support, see Section 12.3.5.4.5,
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 (MMCSD1 only)
