eMMC Interface

eMMC Interface
The ADSP-BF518F processor is equipped with a removable storage inter-
face (RSI), which allows the 2 Gb Micron eMMC flash memory device to
be attached gluelessly to the processor. The eMMC interface is attached
via the processor's specific RSI control and data lines. The eMMC inter-
face shares pins with the secure digital (SD) interface, push buttons,
analog-to-digital converter (ADC) and expansion interface II.
The RSI signals can be disconnected from the eMMC interface by turning
switches and

An example program is included in the EZ-Board installation directory to
demonstrate how to setup and access the eMMC interface.

SD Interface

The ADSP-BF518F processor has a secure digital interface. The SD inter-
face consists of a clock pin, a command pin, a card detect pin, and a
four-bit data bus. The SD interface of the processor connects gluelessly to
the on-board SD connector. The SD interface is attached via the proces-
sor's specific RSI control and data lines. The interface shares pins with the
eMMC interface, codec, and expansion interface II. The memory can be
written to in one-bit and four-bit modes. For more information, refer to
"SD Connector (J13)" on page
the EZ-Board installation directory to demonstrate how to setup and
access the SD interface.
