A rapid change in supply voltage might activate power on reset.
When the supply voltage needs to be varied while operating, it is recommended to minimize
fluctuations to smoothly start up the voltage.
It is recommended to keep the rising
inclination less than 50 mV/ms.
When turning on the power, start the RST pin in
“L” level state, allow as much time as for tRSTL after
reaching the VCC power supply level and then set
the pin to the H level.
