Note : The above values are used for causing a power-on reset.
Some registers in the device are initialized only upon a power-on reset. To initialize these registers, turn the
power supply on using the above values.

Sudden changes in the power supply voltage may cause a power on reset. We
recommend to raise the voltage smoothly to suppress fluctuation during operation,
as shown in the figure below. Perform while not using the PLL clock. However, if
voltage drops are within 1 V/s, you can operate while using the PLL clock.
We recommend rising speed
of the supply voltage at 50
mV/ms or slower
