timer operates, the internal low-speed oscillation clock does not stop, even in case of a program loop.
5.4.5 Prescaler
The internal high-speed oscillator is incorporated in the 78K0R/KE3 (8 MHz (TYP.)). Oscillation can be controlled
After a reset release, the internal high-speed oscillator automatically starts oscillation.
The internal low-speed oscillator is incorporated in the 78K0R/KE3.
The internal low-speed oscillation clock is used only as the watchdog timer clock.
After a reset release, the internal low-speed oscillator automatically starts oscillation, and the watchdog timer is
The internal low-speed oscillator continues oscillation except when the watchdog timer stops. When the watchdog
The prescaler generates CPU/peripheral hardware clock by dividing the main system clock and subsystem clock.
