for reset and power management features. Some features are affected by registers
described in other chapters.
Address (Hex)
Power-On Reset—Starts the oscillator and internal clock and initializes the system to
its power-on reset defaults.
Voltage Brownout Standby—Stops the oscillator and internal clock if a low-voltage
condition occurs. Initiates a Power-On Reset when power is restored.
Voltage Detection—Optionally sets a Flag if a Low- or High-voltage condition occurs.
The low-voltage detection Flag can generate an interrupt request, if enabled.
HALT Mode—Stops the internal clock to the CPU until an enabled interrupt request is
received.
STOP Mode—Stops the clock and oscillator, reducing the MCU supply current to a
very low level until a Power-On Reset or Stop Mode Recovery occurs.
Stop Mode Recovery—Restarts the oscillator and internal clock and initializes most of
the system to its power-on reset defaults. Some register values are not reset by a Stop
Mode Recovery.
Watchdog Timer—Optionally generates a Power-On Reset if the program fails to
execute the WDT instruction within a specified time interval.
