Function 
Description 
Sets up Interrupt Service Routine (ISR). When an interrupt arrives, the ISR will be called automatically. This interrupt service cannot preempt execution. When the next interrupt arrives, it will wait for ISR to finish the previous interrupt before its execution starts. There are two external interrupts on LinkIt One development board, interrupt 0 (at pin 2) and interrupt 1 (at pin 3). 
Disables ISR. 
Disables interrupt (which can be enabled again by interrupts()). 
Enables interrupt (after it is disabled by noInterrupts()). By default, interrupts make some essential tasks executed in background. Disabling interrupts will make some communication functions unable to work normally and external interaction ignored. Therefore, please pay particular attention when using this function and enable the interrupt again as soon as possible
