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

Link activity LED indication. This pin is driven
active when a valid link is detected and blinks
when activity is detected.
Note:
This configuration strap is used to disable the
internal 1.2 V regulator. When the regulator is
disabled, external 1.2 V must be supplied to
VDDCR.
See
configuration straps.
Note:
Link speed LED indication. This pin is driven
active when the operating speed is 100 Mbps. It
is inactive when the operating speed is 10 Mbps
or during line isolation.
Note:
This configuration strap selects the mode of the
nINT/TXER/TXD4 pin.
See
configuration straps.
Note:
When REGOFF is pulled high to VDD2A with
an external resistor, the internal regulator is
disabled.
When REGOFF is floating or pulled low, the
internal regulator is enabled (default).
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.
