In a system where the supply voltage (V
In this system, take the following actions.
The system may be repeatedly reset and released from the reset status.
In this case, the time from release of reset to the start of the operation of the microcontroller can be arbitrarily set
by taking action (1) below.
Interrupt requests may be frequently generated. Take action (2) below.
After releasing the reset signal, wait for the supply voltage fluctuation period of each system by means of a
software counter that uses a timer, and then initialize the ports.
), the operation is as follows depending on how the low-voltage detector is used.
