Because the Port 1 PHY and Port 2 PHY are functionally identical, this section will describe
them as the “Port x PHY”, or simply “PHY”. Wherever a lowercase “x” has been appended
to a port or signal name, it can be replaced with “1” or “2” to indicate the Port 1 or Port 2
PHY respectively. All references to “PHY” in this section can be used interchangeably for
both the Port 1 & 2 PHYs. This nomenclature excludes the Virtual PHY.
