Notes 1.
Cautions 1. A voltage oscillation stabilization time is required after the supply voltage reaches 1.59 V
Remark While the microcontroller is operating, a clock that is not used as the CPU clock can be stopped via

software settings. The internal high-speed oscillation clock and high-speed system clock can be stopped
by executing the STOP instruction (see (4) in 5.6.1 Example of controlling high-speed system clock,
(3) in 5.6.2 Example of controlling internal high-speed oscillation clock, and (3) in 5.6.3 Example
of controlling subsystem clock).
2. It is not necessary to wait for the oscillation stabilization time when an external clock input
The internal reset processing time includes the oscillation accuracy stabilization time of the internal
high-speed oscillation clock.
When releasing a reset (above figure) or releasing STOP mode while the CPU is operating on the
internal high-speed oscillation clock, confirm the oscillation stabilization time for the X1 clock using the
oscillation stabilization time counter status register (OSTC). If the CPU operates on the high-speed
system clock (X1 oscillation), set the oscillation stabilization time when releasing STOP mode using the
oscillation stabilization time select register (OSTS).
(TYP.). If the supply voltage rises from 1.59 V (TYP.) to 2.07 V (TYP.) within the power supply
oscillation stabilization time, the power supply oscillation stabilization time is automatically
generated before reset processing.
