A.3 Chip Power-up and LVI/LVR graphical explanation
Voltage regulator sub modules LVI (low voltage interrupt), POR (power-on reset) and LVR (low voltage
reset) handle chip power-up or drops of the supply voltage. Their function is described in Figure A-1.

A.4 Output Loads
A.4.1 Resistive Loads
The on-chip voltage regulator is intended to supply the internal logic and oscillator circuits allows no
external DC loads.
