GND
At power-up, the voltage on this pin is sensed to configure the
PSE available power, mid span/end span timing mode and the
device's restart behavior when a fault condition is detected. Refer
to "4.2. Operating Mode Configuration" on page 12.
After reading the voltage present at this pin at power-up, the
STATUS pin becomes a digital output used to control an external
LED, which indicates when a detect, power good, or output fault
condition has occurred. Logic high turns the LED on, and logic low
turns the LED off. Refer to "5.7. Status LED Function" on page 14.
