CPU Operating Clock
This section explains the functions of the clock monitor. The start and stop conditions are as follows.
<Start condition>
<Stop conditions>
Notes 1. The internal oscillator can be stopped by setting the RCM.RSTOP bit to 1.
Enabling operation by setting the CLM.CLME bit to 1
• While oscillation stabilization time is being counted after STOP mode is released
• When the main clock is stopped (from when PCC.MCK bit = 1 during subclock operation to when PCC.CLS bit =
• When the sampling clock (internal oscillation clock) is stopped
• When the CPU operates using the internal oscillation clock
2. The clock monitor is stopped while the internal oscillator is stopped.
3. The internal oscillator cannot be stopped by software.
