(3) Example of setting procedure when stopping the internal high-speed oscillation clock
<2> Setting the internal high-speed oscillation clock as the source clock of the CPU/peripheral hardware clock
The internal high-speed oscillation clock can be stopped in the following two ways.
• Executing the STOP instruction
• Setting HIOSTOP to 1
(a) To execute a STOP instruction
<1> Setting of peripheral hardware
<2> Setting the X1 clock oscillation stabilization time after STOP mode is released
<3> Executing the STOP instruction
Note Setting is prohibited when f

Stop peripheral hardware that cannot be used in the STOP mode (for peripheral hardware that cannot be
used in STOP mode, see CHAPTER 21 STANDBY FUNCTION).
If the X1 clock oscillates before the STOP mode is entered, set the value of the OSTS register before
executing the STOP instruction.
When the STOP instruction is executed, the system is placed in the STOP mode and internal high-speed
oscillation clock is stopped.

clock, do so after 10
restarted, the accuracy of the internal high-speed oscillation cannot be guaranteed for 10
