Regulator output voltage
The internal regulator uses pin83/pin92 VCC_O as reference
voltage to control external transistor to generate a voltage
source between 1.80v ~ 2.05v..
If pin 53 EXTMII_EN is pulled high, then pin83/pin92 VCC_O
should be connected to 3.3v to generate 1.80v ~ 2.05v voltage
source.
If pin 53 EXTMII_EN is pulled low, then pin83/pin92 VCC_O
should be connected to 2.5v to generate 1.80v ~ 2.05v voltage
source.
Band gap resister
It is connected to GND through a 6.19k (1%) resistor in
application circuit.
