The low voltage detection is used to detect low battery or low power condition. There are 4 options on the
detection level selectable by mask option MO_DLVL. The low voltage detection circuit can be turned off
by clearing LVDE bit, and the status of supply power can be read out at bit LVDO of LVDC register
(extension register 0x17h).

Low voltage reset circuit prevents the CPU from operating below its physical limit. When the supply
voltage drops below V
DET
(2.2Volt), the CPU will be held in reset state until the supply voltage rises to
V
RLS
. Then CPU will be released from reset state. V
RLS
will be higher than V
DET
by 5% to provide
hysteresis and prevent CPU from bouncing back and forth between reset and operating state. The low
voltage reset function can be enabled or disabled by mask option MO_LVRE.

The voltage detection circuit is temperature compensated to prevent the detection voltage from drifting
with temperature variation.
