SLLU131B – July 2010 – Revised February 2011

SPI

The TUSB9260 supports a SPI interface connected to a SPI flash device. The flash device is used to hold
the firmware for the TUSB9260.

For normal SPI operation a jumper on J13 must be populated. For reprogramming of the SPI flash device
it may be necessary to temporally remove J13. Refer to the TUSB9260 Flash Burner User Guide
(

SLLU125

) for more information about programming the SPI flash.
