This signal is used for testing the analog section of the
chip, and to enable or disable the internal 1.8v regulator.
This pin must be connected to VDDA33 to enable the
internal 1.8V regulator, or to VSS to disable the internal
regulator.
When the internal regulator is enabled, the 1.8V power
pins must be left unconnected, except for the required
bypass capacitors.When the PHY is in test mode, the
internal regulator is disabled and the ATEST pin
functions as a test pin.
+3.3V I/O Power.
If the internal core 1.8V regulator is enabled, then this pin
acts as the regulator input

If the internal regulator is enabled, then VDD18 pin 50
must have a 4.7
