• Programmable Brown-out Reset (BOR) with Software Enable Option
• Alternate Run Modes: By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be reduced by as much as 90%.
• Multiple Idle Modes: The controller can also run with its CPU core disabled but the peripherals still active. In these states, power consumption can be reduced even further, to as little as 4% of normal operation requirements.
• On-the-Fly Mode Switching: The powermanaged modes are invoked by user code during operation, allowing the user to incorporate power-saving ideas into their app
