16.3 Low Voltage Detection Mode
(1) Low voltage detection condition
An on board voltage comparator checks that VDD is at the
required level to ensure correct operation of the device. If
VDD is below a certain level, Low voltage detector forces
the device into low voltage detection mode.
(2) Low Voltage Detection Mode
There is no power consumption except stop current, stop
mode release function is disabled. All I/O port is config-
ured as input mode and Data memory is retained until volt-
age through external capacitor is worn out. In this mode,
all port can be selected with Pull-up resistor by Mask op-
tion. If there is no information on the Mask option sheet
,the default pull up option (all port connect to pull-up resis-
tor ) is selected.
(3) Release of Low Voltage Detection Mode
Reset signal result from new battery(normally 3V) wakes
the low voltage detection mode and come into normal reset
state. It depends on user whether to execute RAM clear
routine or not
