I'm trying to locate a programmers guide for the TUSB9261. To make a long story short we use the TUSB9261 in a product and have a version of the software that's been used. I'm now trying to make some modifications and have many questions about the chip and how it's programmed. I'm looking for things like register layout, data path memory configuration, interrupts, etc. Basic information needed to program any MCU. I saw that TI no longer provides the software, just the binary image for the firmware. I'm hoping there's a document available.
