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~V
LVR
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~V
LVR
) 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.
The relationship between V

*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.
