The subclock operation mode is set by setting the PCC.CK3 bit to 1 in the normal operation mode.
When the subclock operation mode is set, the internal system clock is changed from the main clock to the subclock.
When the PCC.MCK bit is set to 1, the operation of the main clock oscillator is stopped. As a result, the system
In the subclock operation mode, the power consumption can be reduced to a level lower than in the normal operation
Table 25-10 shows the operating status in subclock operation mode.
Cautions 1. When manipulating the CK3 bit, do not change the set values of the PCC.CK2 to PCC.CK0 bits
Remark Internal system clock (f
The subclock operation mode is released by a reset signal (reset by RESET pin input, WDT2RES signal, low-voltage
If the main clock is stopped (MCK bit = 1), set the MCK bit to 1, secure the oscillation stabilization time of the main
The normal operation mode is restored when the subclock operation mode is released.
Caution When manipulating the CK3 bit, do not change the set values of the CK2 to CK0 bits (using a bit
2. If the following conditions are not satisfied, change the CK2 to CK0 bits so that the conditions are
