5.6.2 Example of controlling internal high-speed oscillation clock

(1) When restarting oscillation of the internal high-speed oscillation clock
(2) When using internal high-speed oscillation clock as CPU clock, and internal high-speed oscillation clock or
(3) When stopping the internal high-speed oscillation clock
(1) Example of setting procedure when restarting oscillation of the internal high-speed oscillation clock
The following describes examples of clock setting procedures for the following cases.
(b) To stop X1 oscillation (disabling external clock input) by setting MSTOP to 1
high-speed system clock as peripheral hardware clock
<1> Setting restart of oscillation of the internal high-speed oscillation clock (RCM register)
<2> Waiting for the oscillation accuracy stabilization time of internal high-speed oscillation clock (RCM
Notes 1. After a reset release, the internal high-speed oscillator automatically starts oscillating and the
<1> Confirming the CPU clock status (PCC and MCM registers)
<2> Stopping the high-speed system clock (MOC register)
Caution Be sure to confirm that MCS = 0 or CLS = 1 when setting MSTOP to 1. In addition, stop
When RSTOP is cleared to 0, the internal high-speed oscillation clock starts operating.

Confirm with CLS and MCS that the CPU is operating on a clock other than the high-speed system
clock.
When CLS = 0 and MCS = 1, the high-speed system clock is supplied to the CPU, so change the
CPU clock to a clock other than the high-speed system clock.
When MSTOP is set to 1, X1 oscillation is stopped (the input of the external clock is disabled).
