(3) Power-on reset
(VCC
= AVCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V, TA = 40 °C to + 85 °C)
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 procedure must be obeyed by these value.
Note : 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.
