5.4.6 LVR Operation in Stop and Wait Modes
Advance Information
minimum operating voltage of the microcontroller and is intended to
assure that the CPU will be held in reset when the V
below reasonable operating limits. A mask option is provided to disable
the LVR when the device is expected to normally operate at low
voltages. Note that the V
must be within the specification for proper LVR operation. If the
specification is not met, the circuit will operate properly following a delay
of V
The LVR will generate the RST signal which will reset the CPU and other
peripherals. The low-voltage reset will activate the internal pulldown
device connected to the RESET pin.
If any other reset function is active at the end of the LVR reset signal, the
RST signal will remain in the reset condition until the other reset
condition(s) end.
If enabled, the LVR supply voltage sense option is active during stop and
wait modes. Any reset source can bring the MCU out of stop or wait
mode.
