A.5
A.5.1
The voltage regulator is intended to supply the internal logic and oscillator. It allows no external DC loads.
A.5.2
The capacitive loads are specified in
A.5.3
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
