The interrupt controller on Z8 Encore! XP
requests from the on-chip peripherals and the GPIO port pins. The features of the interrupt
controller include the following:
Interrupt Requests (IRQs) allow peripheral devices to suspend CPU operation in an
orderly manner and force the CPU to start an Interrupt Service Routine (ISR). Usually this
ISR is involved with the exchange of data, status information, or control information
between the CPU and the interrupting peripheral. When the service routine is
completed, the CPU returns to the operation from which it was interrupted.
The eZ8 CPU supports both vectored and polled interrupt handling. For polled interrupts,
the interrupt control has no effect on operation. For more information on interrupt servic-
ing, refer to eZ8 CPU Core User Manual (UM0128) available for download at
www.zilog.com.
