5.2.3 Interrupt
For your understanding of Interrupt function, here describes program setting method of XG5000 which is an XGB
programming S/W. Example of interrupt setting is as shown bellows.

Remark
 In case that several tasks to be executed are waiting, execute from the highest Task Program in
priority. When the same priority tasks are waiting, execute from the order occurred.
 While interrupt executing, if the highest interrupt is occurred, the highest interrupt is executed earliest of
all.
 When power On, All interrupts are in the state „Enable‟. In case you don‟t use it, disable the
interrupts by using DI instruction. If you want to use it again, enable by using EI instruction.
 Internal device interrupt is executed after END instruction.
