2.10 SPI interface
The T2080RDB-PC Serial Peripheral Interface (SPI) pins is only used for onboard SPI
device accessing various SPI memory devices.
2.11 Local bus
The T2080 Integrated Flash Controller (IFC), also known as the local bus, supports 32-bit
addressing and 8 or 16-bit data widths for a variety of devices to effectively manage all
these resources with the maximum amount of performance and flexibility.
The image below shows an overview of the IFC bus.

2.12 SDHC interface
The enhanced SD Host Controller (eSDHC) provides an interface between host system
and SD cards. The Secure Digital (SD) card is specifically designed to meet the security,
capacity, performance, and environmental requirements, inherent in emerging audio and
video consumer electronic devices. Booting from eSDHC interface is supported using the
processor’s on-chip ROM.
