Notes :
The above rating values are for generating a power-on reset.
When HST

a power-on reset is required.
Some internal registers are only initialized by a power-on reset. Always apply the power supply in cordance
with the above ratings if you wish to initialize these registers.

Recommended rate of voltage
rise is 50 mV/ms or less.
Sudden changes in the power supply voltage may cause a power-on reset.
The recommended practice if you wish to change the power supply voltage while the device is operating is
to raise the voltage smoothly as shown below. Also, changes to the supply voltage should be performed when
the PLL clock is not in use. The PLL clock may be used, however, if the rate of voltage change is 1 V/s or less.
