(4) Example of setting procedure when stopping the high-speed system clock
<3> If some peripheral hardware macros are not used, supply of the input clock to each hardware macro can
The high-speed system clock can be stopped (disabling clock input if the external clock is used) in the following
two ways.
• Executing the STOP instruction
• Setting MSTOP to 1
(a) To execute a STOP instruction
<1> Setting to stop peripheral hardware
<2> Setting the X1 clock oscillation stabilization time after STOP mode is released
<3> Executing the STOP instruction
be stopped.
(PER0 register)
Remark RTCEN:
Caution Be sure to clear bits 1 and 6 of PER0 register to 0.

Stop peripheral hardware that cannot be used in the STOP mode (for peripheral hardware that
cannot be used in STOP mode, see CHAPTER 17 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 X1 oscillation is
stopped (the input of the external clock is disabled).
