Configuration strap values are latched on power-on reset and system 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

When nINTSEL is floated or pulled to VDD2A,
nINT is selected for operation on the
nINT/TXER/TXD4 pin (default).
When nINTSEL is pulled low to VSS,
TXER/TXD4 is selected for operation on the
nINT/TXER/TXD4 pin.
