1 This is an active low signal but the signal name does not show this.
2 This signal defaults to an input setting, putting the signal in High-Z. Must be used in concert with PHY-
INT_EN. Set PHYINT_EN high first and then control PHY_PWR_DWN_INT.
3 This signal defaults to an input setting, putting the signal in High-Z. There is a 2.21k resistor pull-up,
which sets the PHY address appropriately. If isolate mode is desired, the signal needs to be set as an out-
put and driven appropriately.
