DS90UB953/954 System Design & Operation: Basic Design Rules
Understanding what hardware and software settings are important is critical to establishing a foundation for the 953/954 system. These settings can occur during or after power up and may need to be changed via software. As a result, these settings are routinely checked and verified before checking any of the other links in the system.
