10. RESET FUNCTION
10.1 Configuration and Operation Status of RESET Function
There are three kinds of reset input: the external reset signal (RESET), the reset signal sent from the basic interval/
watchdog timer, and the reset signal generated by a falling edge signal from KRn in the STOP mode. When any of
these reset signals is input, an internal reset signal is generated. The configuration is shown in Figure 10-1.
