(3) Power-on reset
(VCC
= AVCC = 3.3 V ± 0.3 V, Ta = 40 to + 85 °C)
The Power-on reset is based on VSS
= AVSS = 0.0 V.
Notes :
VCC should be set under 0.2 V before power-on rising up.
These value are for power-on reset.
In the device, there are internal registers which is initialized only by a power-on reset. If these initialization
is executing, power-on prosedure must be obeyed by these value.

Sudden change of power supply voltage may activate the power-on reset function. When changing
power supply voltages during operation, raise the power smoothly by suppressing variation of
voltages as shown below. When raising the power, do not use PLL clock. However, if voltage drop is
1mV/s or less, use of PLL clock is allowed during operation.
RAM data hold
Limiting the slope of rising within
50 mV/ms is recommended.
