Compliant with the following specifications:

• JEDEC eMMC Specification Version 5.1.
• AMBA, Advanced Extensible Interface (AXI) Specification Version 4.0.
• AMBA, Advanced Peripheral Bus (APB) Specification Version 2.0.

The Host controller supports:

• 32-bit and 64-bit system data bus.
• 32-bit and 64-bit system addressing.
• 64 and 128 bit DMA Descriptor length.
• Interrupts functionality.
• Supports both Asynchronous and Synchronous AXI4 Interface: The Master and the Host Controller operate at the same clock rate or different clock rates.

The data is transferred using:

• Programmed Input/Output (PIO) mode on the Host Bus Slave interface.
• Direct Memory Access (SDMA and ADMA2) mode on the Host Bus Master interface.
• Configurable FIFO size to support different block sizes 512B and 4KB.

eMMC 5.1 features:

• HS400 high speed interface timing mode of up to 400 MB/s data rate.
• Transfers the data in HS400, HS200, DDR52, SDR52 modes.
• 4KB block support.
• Tuning for HS200 mode.
• Command Queuing for High Performance data transfers with Hardware Acceleration.
• Enhanced strobe function for reliable operation at HS400 mode.
• Host clock rate variable between 0 and 200 MHz.
• Supports 1-bit, 4-bit and 8-bit data interface.
• Supports legacy modes (Default Speed, High Speed).
• CRC7 for command and CRC16 for data integrity.
• Supports multiple boot mode.
