Low Voltage Reset
LVR
The microcontroller contains a low voltage reset circuit
inordertomonitorthesupplyvoltageofthedevice.Ifthe
supply voltage of the device drops to within the range of
0.9V~V
LVR
such as might occur when changing the bat-
tery, the LVR will automatically reset the device inter-
nally.
The LVR includes the following specifications:
ForavalidLVRsignal,alowvoltage(0.9V~V
LVR
)must
exist for more than 1ms. If the low voltage state does
not exceed 1ms, the LVR will ignore it and will not per-
form a reset function.
The LVR uses the OR function with the external
RES signal to perform a 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: A low voltage has to exist for more than 1ms, after that 1ms delay, the device enters a reset mode.
