public class Decrementer
extends IrqInterrupt

The class for the ARM private timer. This timer is used to count backwards. As soon as zero is reached the counter is reloaded with its initial value and an interrupt is generated. The private timer is clocked with half of the CPU frequency (CPU_3x2x). You can extend this class to define your own timer class, e.g. to run a control loop. Keep in mind, that the action method is called from the interrupt handler. If you use the floating point unit, you have to make sure that the floating point registers get saved upon entering the action method, see \ref US.ENABLE_FLOATS.
