The operation guaranteed range is 1.8 V ≤ V
state when the supply voltage falls, use the reset function of the low-voltage detector, or input the low
level to the RESET pin.
If the rate at which the voltage rises to 1.8 V after power application is slower than 0.5 V/ms (MIN.),
input a low level to the RESET pin before the voltage reaches to 1.8 V, or set LVI to ON by default by
using an option byte (option byte: LVIOFF = 0).
The internal voltage stabilization time includes the oscillation accuracy stabilization time of the internal
high-speed oscillation clock.
The internal reset processing time includes the oscillation accuracy stabilization time of the internal
high-speed oscillation clock.
The internal high-speed oscillation clock and a high-speed system clock or subsystem clock can be
selected as the CPU clock. To use the X1 clock, use the OSTC register to confirm the lapse of the
oscillation stabilization time. To use the XT1 clock, use the timer function for confirmation of the lapse
of the stabilization time.
