Electrical Characteristics
A.5 Output Loads
A.5.1 Resistive Loads
The voltage regulator is intended to supply the internal logic and oscillator. It allows no external DC loads.
A.5.2 Capacitive Loads
The capacitive loads are specified in Table A-19. Ceramic capacitors with X7R dielectricum are required.

A.5.3 Chip Power-up and Voltage Drops
LVI (low voltage interrupt), POR (power-on reset) and LVRs (low voltage reset) handle chip power-up or
drops of the supply voltage. Their function is shown in Figure A-2 .
