When the battery's charge level drops below this value, the device should automatically begin taking action to conserve power. A typical value for this field is 40, indicating that the battery is 40 percent charged.

Specifies the delay that is required to keep the battery in idle charging mode.

A battery's hysteresis comparator senses a charging current flowing through the battery pack and turns off the charge when the current reaches an upper limit (maximum voltage level). Because the charging current may fluctuate slightly, it is possible for the comparator to detect that the voltage level has reached the maximum when a transitory spike occurs. Therefore, chargers use a hysteresis delay. After the comparator detects the maximum voltage level, the charger waits the number of milliseconds specified in this field before turning off the charging current. If the voltage level drops below the maximum during the hysteresis delay, the charger does not turn off the charging voltage.

Represents an instance of the class.

The class is for use with GPIO pins that can be both input and output pins. It has nothing to do with tristate voltage levels in hardware. A pin is considered "active" when it is an output pin. It is an input pin when it is in the "inactive" state. Your application can use the class to control and monitor whether a particular GPIO pin is currently an input pin or an output pin. Note that tristate ports can share pins with other tristate ports, for both reading and writing. This class cannot be inherited.

Gets a value that indicates whether the glitch filter is currently enabled.

Represents an interrupt port.

This class cannot be inherited. When configuring an interrupt port, note the differences between level and nonlevel interrupts. Level interrupts, which are either or interrupts, are dispatched when the value on a pin matches the specified high value or low value, respectively. The system dispatches only the first occurrence of a level interrupt until it is cleared by means of the ClearInterrupt method. With nonlevel interrupts, every specified edge is dispatched, and the ClearInterrupt method has no effect. In practice, it is best to use level interrupts when the interrupt condition needs to be checked only periodically. It is possible to configure an object into an invalid state. In such cases, your program may not generate an exception until it actually uses the object. For example, suppose you create an object with its resistor mode set to , the interrupt mode set to , and the glitch filter set to true. This configuration does not generate an exception when you instantiate an object. If you then add an interrupt handler, the .NET Micro Framework throws an exception.
