Clock monitor status
(1) Operation when main clock oscillation is stopped (CLME bit = 1)
(2) Clock monitor status after RESET input
Internal oscillation
Internal oscillation
RESF.CLMRF bit
(CLM.CLME bit = 1 is set after RESET input and at the end of main clock oscillation stabilization time)
CLM.CLME bit
If oscillation of the main clock is stopped when the CLME bit = 1, an internal reset signal is generated as
shown in Figure 23-2.
RESET input clears the CLM.CLME bit to 0 and stops the clock monitor operation. When CLME bit is set to 1
by software at the end of the oscillation stabilization time of the main clock, monitoring is started.
