Chip Power Up and Voltage Drops
The VREG 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. Refer to Figure 2.

Output Loads
The on-chip voltage regulator is intended to supply the internal logic and oscillator circuits. No external DC
load is allowed. Capacitive loads are specified in Table 14. Capacitors with X7R dielectricum are required.
