Low voltage reset
LVR
The microcontroller provides low voltage reset circuit in
order to monitor the supply voltage of the device. If the
supply voltage of the device is within the range
0.9V~3.3V, such as changing a battery, the LVR will au-
tomatically reset the device internally.
The LVR includes the following specifications:
The low voltage (0.9V~3.3V) has to remain in their
original state to exceed 1ms. If the low voltage state
does not exceed 1ms, the LVR will ignore it and do not
perform a reset function.
The LVR uses the OR function with the external RES
signal to perform chip reset.

Low voltage reset
Note:
*1: To make sure that the system oscillator has stabilized, the SST provides an extra delay of 1024 system
clock pulses before entering the normal operation.
*2: Since low voltage state has to be maintained in its original state for over 1ms, therefore after 1ms delay,
the device enters the reset mode.
