4.3.1 Power-On Reset
A positive transition on the VDD pin generates a power-on reset.
NOTE:
The power-on reset is strictly for power-up conditions and cannot be
used to detect drops in power supply voltage.
A 4064-tcyc (internal clock cycle) delay after the oscillator becomes
active allows the clock generator to stabilize. If any reset source is active
at the end of this delay, the MCU remains in the reset condition until all
reset sources are inactive.
