the 2.5V regulator to power AVDDC.
1.2V Regulator supply - 2.5V
AVDDR can be supplied externally with 2.5V, or via
the 2.5V regulator. If the 1.2V regulator is not used,
AVDDR must still be tied to 2.5V.
2.5V Regulator supply - 3.3V
AVDDX must be supplied externally. Note that this
supply must be the same voltage as AVDDC.
If the 2.5V regulator is not used, then it means a
