Note 3.2

Configuration strap values are latched on Power-On Reset (POR) and the rising edge of

RESET_N (external chip 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 6.3, "Device Configuration

Straps," on page 26 for additional information.
