(4) Power-on reset
(VCC
= AVCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V, TA = 40 °C to +85 °C)
Notes :
VCC must be lower than 0.2 V before the power supply is turned on.
The above standard is a value for performing a power-on reset.
In the device, there are internal registers which is initialized only by a power-on reset.
When the initialization of these items is expected, turn on the power supply according to the standards.
Sudden change of power supply voltage may activate the power-on reset function.
When changing the power supply voltage during operation as illustrated below, voltage fluctuation should
be minimized so that the voltage rises as smoothly as possible. When raising the power, do not use PLL
clock. However, if voltage drop is 1 V/s or less, use of PLL clock is allowed during operation.
