(1) Classification is tested with exact resistor values. A 1% tolerance classification resistor ensures compliance with IEEE 802.3af limits.
(2) This parameter specifies the RTN current value, as a percentage of the steady state inrush current, below which it must fall to make PG
assert (open-drain).
