(3) Operation
Internal reset signal
When the supply voltage and detection voltage are compared and if the supply voltage is lower than the
detection voltage (including at power application), the system is reset and each hardware is returned to the
specific status.
The system is reset from when low voltage is detected until the supply voltage becomes higher than the
detection voltage. After a reset is released, when the oscillation stabilization time (default value of the OSTS
register: 2
The oscillator stops during a reset, so secure the oscillation stabilization time.
The status of each hardware during the reset period and after reset release is the same as the reset operation
by the RESET pin (see 16.3.1 Reset operation via RESET pin).
The following shows the timing chart.
