Clock monitor status
Internal reset signal
(1) Operation when main clock oscillation is stopped (CLME bit = 1)
(2) Clock monitor status after RESET input
Internal oscillator
RESF.CLMRF bit
Internal oscillator
CLM.CLME bit
If oscillation of the main clock is stopped when the CLME bit is 1, an internal reset signal is generated as
shown in Figure 25-2.
RESET input clears the CLM.CLME bit to 0 and stops the clock monitor operation. When the CLME bit is set
to 1 by software after the normal operation is started, monitoring is started.
