2.10 SPI interface
The T2080RDB-PC Serial Peripheral Interface (SPI) pins are 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 various 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 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 on-chip ROM of the processor.
On T2080RDB-PC, a single connector is used for MicroSD memory cards, as shown in the image below.
