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
withintherange0.9V~3.3V,suchaschanginga
battery, the LVR will automatically 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 func-
tion.
TheLVRusesthe OR functionwiththeexter-
nal RES signal to perform chip reset.
