Note 1:
Note 2:
RBIAS is connected to the Analog Ground plane VSSA(REF) via a resistor.
When the internal 1.8V regulator is enabled, VDDCORE (91) and VDDP(98), MUST have a 10uf +/- 20%,
(equivalent series resistance (ESR) <0.1ohm) bypass capacitor to VSSA.
VDDA(REF) and VSSA(REF) are same as the VDDA and VSSA respectively.
