Most of LDD components are designed to be used in the interrupt mode. It means that the interrupt service routine (ISR) is called by the interrupt controller when an asynchronous interrupt occurs. Interrupt service routine is defined in LDD driver and a user is notified through component's events. Events can be enabled or disable in the component inspector according to an application needs. When an event is enabled, the appropriate function is generated into Event.c, where a user can write own event handler code. Events are called from the ISR context, so a user should keep an event code as short as possible to minimize a system latency.
