Software Interrupt
The master interrupt enable bit (IRQE) in the Interrupt Control Register globally enables
and disables the interrupts.
Interrupts are globally enabled by any of the following actions:
•
•
Execution of an EI (enable interrupt) instruction
Execution of an IRET (return from interrupt) instruction
