Cautions 1. To use the peripheral hardware that stops operation in the STOP mode, and the peripheral
2. Even if “internal low-speed oscillator can be stopped by software” is selected by the option
3. To shorten oscillation stabilization time after the STOP mode is released when the CPU operates
4. Execute the STOP instruction after having confirmed that the internal high-speed oscillator is
hardware for which the clock that stops oscillating in the STOP mode after the STOP mode is
released, restart the peripheral hardware.
byte, the internal low-speed oscillation clock continues in the STOP mode in the status before
the STOP mode is set. To stop the internal low-speed oscillator’s oscillation in the STOP mode,
stop it by software and then execute the STOP instruction.
with the high-speed system clock (X1 oscillation), switch the CPU clock to the internal high-
speed oscillation clock before the execution of the STOP instruction using the following
procedure.
<1> Set RSTOP to 0 (starting oscillation of the internal high-speed oscillator)
to 0 (switching the CPU from X1 oscillation to internal high-speed oscillation)
MCS is 0 (checking the CPU clock)
oscillation operation)
Before changing the CPU clock from the internal high-speed oscillation clock to the high-speed
system clock (X1 oscillation) after the STOP mode is released, check the oscillation stabilization
time with the oscillation stabilization time counter status register (OSTC).
operating stably (RSTS = 1).
<5> Execute the STOP instruction
