Note 2.2
Configuration strap values are latched on hardware reset. Configuration straps are
identified by an underlined symbol name. Signals that function as configuration straps must
be augmented with an external resistor when connected to a load. Refer to Section 3.8,
"Configuration," on page 29 for additional information.
